Atlassian's popular JIRA issue management system takes advantage of the OSUser framework and can quickly be configured to use OSUser to link in single or multiple directory servers through Crowd. Crowd provides integration libraries for the OpenSymphony OSUser module, which has a simple-to-use API for user-management that allows pluggable implementations. More about the OSUser API can be reviewed at http://www.opensymphony.com/osuser/.
Currently Crowd supports centralised authentication and single sign-on for JIRA versions 3.7.4 and later.

If you are using NTLM for Windows authentication, you may want to read about configuring Crowd's JIRA NTLM plugin for single sign-on. |
Prerequisites
- Download and install Crowd. Refer to the Crowd installation guide for detailed information on how to do this. We will refer to the Crowd root folder as CROWD.
- Download and install JIRA (version 3.7.4 or later). Refer to the JIRA installation guide for detailed information on how to do this. We will refer to the JIRA root folder as JIRA. For the purposes of this document, we will assume that the 'standalone' (i.e. the easier and recommended) installation method of JIRA has been used. If you need to install JIRA as an EAR/WAR, simply explode the EAR/WAR and make the necessary changes as described below, and repackage the EAR/WAR.
- Make sure JIRA is not running when you begin the integration process described below.
Step 1. Configuring Crowd to talk to JIRA
1.1 Prepare Crowd's Directories/Groups/Users for JIRA
The JIRA application will need to locate users from a directory configured in Crowd. You will need to set up a directory in Crowd for JIRA. For information on how to do this, see Adding a Directory. We will assume that the directory is called JIRA Directory for the rest of this document. It is possible to assign more than one directory for an application, but for the purposes of this example, we will use JIRA Directory to house JIRA users.
JIRA also requires particular groups to exist in the directory in order to authenticate users. You need to ensure that these three groups exist in the JIRA Directory:
- jira-users
- jira-developers
- jira-administrators
You also need to ensure that the JIRA Directory contains at least one user who is a member of all three groups. You can either:
- If you have an existing JIRA deployment and would like to import existing groups and users into Crowd, use the JIRA Importer tool by navigating to Users > Import Users > Atlassian Importer. Select 'JIRA' as the Atlassian Product and the JIRA Directory as the directory into which JIRA users will be imported. For details please see Importing Users from Atlassian JIRA.
If you are going to import users into Crowd, you need to do this now before you proceed any further.
OR:
- If you don't wish to import your JIRA users, use the Crowd Administration Console to create the three groups, then create at least one user in the JIRA Directory and add them to the three JIRA-specific groups (above). The Crowd documentation has more information on creating groups, creating users and assigning users to groups.
1.2 Define the JIRA Application in Crowd
Crowd needs to be aware that the JIRA application will be making authentication requests to Crowd. We need to add the JIRA application to Crowd and map it to the JIRA Directory.
- Log in to the Crowd Administration Console and navigate to Applications > Add Application.
- Fill out the form to add the JIRA application:

Attribute |
Description |
Name |
The username which the application will use when it authenticates against the Crowd framework as a client. This value must be unique, i.e. it cannot be used by more than one application client. |
Description |
A short description of the application. Note: A web URL is often helpful. |
Active |
Only deselect this if you wish to prevent all users (from all directories) from accessing this application. |
Password |
The password which the application will use when it authenticates against the Crowd framework as a client. |
Confirm Password |
Retype the same password as above, to confirm it. |
Default Directory |
A directory that contains relevant users. Note: Additional directories can be added later. |
The Name and Password values must match the application.name and application.password that you set in the JIRA/atlassian-jira/WEB-INF/classes/crowd.properties (see Step 2 below).
1.3 Specify which users can log in to JIRA
Now that Crowd is aware of the JIRA application, Crowd needs to know which directories or users can authenticate (log in) via Crowd. You can either allow entire directories to authenticate, or just particular groups within the directories. In our example, we will allow the jira-users, jira-developers and jira-administrators groups within the JIRA Directory to authenticate:

With this example, only users who are members of the jira-users, jira-developers and jira-administrators groups will be able to authenticate against JIRA.
For details please see Specifying which Groups can access an Application.
1.4 Specify the address from which JIRA can log in to Crowd
Please see Specifying an Application's Address or Hostname. Please note:
- If JIRA is on a different host to Crowd
If you are running the JIRA on a different host to Crowd, you will need to modify the permissible hosts via the Remote Addresses tab. This lists the hosts/IP addresses that are allowed to authenticate to Crowd. If JIRA is remote to Crowd, add the IP address of your JIRA server and ensure the "Status" field is set to "true". Remove the entry for localhost.
- If JIRA is on the same host as Crowd
By default, when you add an application, localhost is a permissible foreign host. However, you will also need to manually add the IP address 127.0.0.1, as incoming requests to Crowd from JIRA (both on the same, local, host) may be from the host 127.0.0.1 and not localhost. Crowd does not do a DNS lookup of the hostname, rather, it compares the values as is. Ensure the "Status" field is set to "true".
Step 2. Configuring JIRA to talk to Crowd
2.1 Install the Crowd Client Libraries into JIRA
JIRA needs Crowd's client libraries in order to be able to delegate user authentication to the Crowd application. As stated earlier, we are going to be modifying the JIRA application by editing the standalone application, which is an exploded WAR stored in JIRA/atlassian-jira.
- Copy the Crowd client libraries and configuration files to JIRA:
Copy From |
Copy To |
CROWD/client/crowd-integration-client-X.X.X.jar |
JIRA/atlassian-jira/WEB-INF/lib |
CROWD/client/conf/crowd.properties |
JIRA/atlassian-jira/WEB-INF/classes |
- Edit JIRA/atlassian-jira/WEB-INF/classes/crowd.properties. Change the following properties:
Key |
Value |
application.name |
jira |
application.password |
set a password |
crowd.server.url |
http://localhost:8095/crowd/services/ |
session.validationinterval |
Set to 0, if you want authentication checks to occur on each request. Otherwise set to the number of minutes between request to validate if the user is logged in or out of the Crowd SSO server. Setting this value to 1 or higher will increase the performance of Crowd's integration. |
If your Crowd server's port is configured differently from the default (i.e. 8095), set it accordingly. The application.name and application.password must match the Name and Password that you specified when you defined the application in Crowd (see Step 1 above).
 | Passing crowd.properties as an environment variable
You can pass the location of a client application's crowd.properties file to the client application as an environment variable when starting the client application. This means that you can choose a suitable location for the crowd.properties file, instead of putting it in the client application's WEB-INF/classes directory.
This applies to the Crowd Administration Console's crowd.properties file too. You may find this particularly useful when integrating with a WAR deployment of an integrated application.
Example:
-Dcrowd.properties={FILE-PATH}/crowd.properties
|
2.2 Configure JIRA to use Crowd's Authenticator
Now that the Crowd client libraries exist, we need to configure JIRA to use them.
- Edit the JIRA config file JIRA/atlassian-jira/WEB-INF/classes/osuser.xml. Comment out any existing authentication providers and uncomment/insert the Crowd providers:
<!-- This is where JIRA's credentials checking can be configured. For instance, see
http://www.atlassian.com/software/jira/docs/latest/ldap.html -->
<opensymphony-user>
<authenticator class="com.opensymphony.user.authenticator.SmartAuthenticator" />
<provider class="com.atlassian.crowd.integration.osuser.CrowdCredentialsProvider"/>
<provider class="com.atlassian.crowd.integration.osuser.CrowdAccessProvider"/>
<provider class="com.atlassian.crowd.integration.osuser.DelegatingProfileProvider">
<property name="provider-1">com.atlassian.crowd.integration.osuser.CrowdProfileProvider</property>
<property name="provider-2">com.atlassian.jira.user.ExternalEntityJiraProfileProvider</property>
<property name="provider-2-exclusive-access">true</property>
</provider>
<!--
<provider class="com.atlassian.core.ofbiz.osuser.CoreOFBizCredentialsProvider">
<property name="exclusive-access">true</property>
</provider>
<provider class="com.opensymphony.user.provider.ofbiz.OFBizProfileProvider">
<property name="exclusive-access">true</property>
</provider>
<provider class="com.opensymphony.user.provider.ofbiz.OFBizAccessProvider">
<property name="exclusive-access">true</property>
</provider>
-->
</opensymphony-user>
- View JIRA/atlassian-jira/WEB-INF/classes/propertyset.xml. If an entry doesn't exists for the CrowdPropertySet, to add the following <propertyset> at the end of the file as the last <propertyset>:
<propertyset name="crowd" class="com.atlassian.crowd.integration.osuser.CrowdPropertySet"/>
- At this stage, JIRA is set up for centralised authentication. If you wish, you can now enable single sign-on (SSO) to JIRA.
Skip this step if you are using the JIRA NTLM plugin to enable SSO. Instead, follow the instructions on configuring JIRA for NTLM SSO.
Edit JIRA/atlassian-jira/WEB-INF/classes/seraph-config.xml. Change the authenticator node to read:
<authenticator class="com.atlassian.crowd.integration.seraph.JIRAAuthenticator"/>
JIRA's authentication and access request calls will now be performed using Seraph. Now when authentication or access request calls are performed versus the OSUser framework, the JIRA stack will call the Crowd providers and propertyset implementations.
2.3 Enable JIRA's 'External User Management'
Once the setup is complete, you can configure JIRA to allow external user management. Go to the JIRA Administration Console. In the General Configuration section, turn 'External user management' and 'External password management' on or off. (See the JIRA Administrator's Guide for details).
JIRA with external user management ON:
This is recommended, because it allows you to use Crowd's powerful cross-directory user administration features.
If you turn external user management on, the following functions can no longer be performed from within the JIRA administration interface: adding users, adding groups, editing users, editing groups.
If you are using Crowd 1.1.1 or earlier, you must turn external user management on in JIRA.
JIRA with external user management OFF:
This means that you can allow signup via JIRA, and you can manage your users within JIRA. Changes will flow through to Crowd.
JIRA has an automatic group membership feature. This means that any new user added through JIRA will automatically be a member of all groups which have the JIRA Users permission. In this way, you can ensure that a new user is automatically added to several groups when they sign up with JIRA.
Any group or user changes will cascade to all directories assigned to the JIRA application in Crowd. For example, if user 'jbloggs' registers in JIRA, 'jbloggs' will be added to every Crowd directory linked with the JIRA application.
2.4 (Optional) Tune the Cache
When utilising the atlassian-user and Crowd framework together with JIRA, it is highly recommended that caching be enabled. Multiple redundant calls to the atlassian-user framework are made on any given request. These results can be stored locally between calls by enabling caching via the Crowd Options menu. (Note that this caching in the Crowd application is enabled by default.)
JIRA will obtain all necessary information for the period specified by the cache configuration - see Configuring Caching for an Application. If a change or addition occurs in Crowd to users, groups and roles, these changes will not be visible in JIRA until the cache expires for that specific item (i.e. for the particular user, group or role).
The default value for the application cache is 5 minutes (300 seconds). To increase the performance of your application, consider changing the cache value to one or two hours (3600 or 7200 seconds).
2.5 (Optional) Disable the Auto-Complete Function in JIRA's User Picker
To improve performance on page-loading in JIRA, we recommend that you disable the auto-complete function in JIRA's 'User Picker' popup screens. Follow the instructions in the JIRA documentation.
More information: In our experience, disabling this feature in JIRA helps performance for customers with extremely large user bases. If you leave this feature enabled and have adequate performance results in JIRA, feel free to leave it enabled.
See Crowd in Action
- You should now be able to login using users belonging to the jira-users group. Try adding a user to the group using Crowd — you should be able to login to JIRA using this newly created user. That's centralised authentication in action!
- If you have enabled SSO, you can try adding the JIRA Directory and jira-administrators group to the crowd application (see Mapping a Directory to an Application and Specifying which Groups can access an Application). This will allow JIRA administrators to log in to the Crowd Administration Console. Try logging in to Crowd as a JIRA administrator, and then point your browser at JIRA. You should be logged in as the same user in JIRA. That's single sign-on in action!
Known Limitations
A problem occurs in JIRA if a user is removed after that user has participated in an issue i.e. if JIRA refers to the user. If the user is internally managed by JIRA, JIRA will prevent the removal of the user but if the user is managed by an external system such as Crowd, JIRA will throw a DataAccessException.
The current workaround for this is to deactivate the user's account (by removing them from the jira-users group). This issue can be tracked here: http://jira.atlassian.com/browse/CWD-202
