Summary

Bamboo does not display all users coming from LDAP if amount of users exceeds MaxPageSize defined in Active Directory.

Environment

• Bamboo v5.14.1
• Windows Active Directory

Steps to Reproduce

1. create a new OU, adding 1501 users:

   dn: CN=bamboo.user0000,OU=users,OU=ps8102,DC=atlassian,DC=local
   cn: bamboo.user0000
   memberOf: CN=bamboo-win-ad,OU=groups,OU=ps8102,DC=atlassian,DC=local
   sAMAccountName: bamboo.user0000
   

   dn: CN=bamboo.user1500,OU=users,OU=ps8102,DC=atlassian,DC=local
   cn: bamboo.user1500
   memberOf: CN=bamboo-win-ad,OU=groups,OU=ps8102,DC=atlassian,DC=local
   sAMAccountName: bamboo.user1500
   

2. connect Bamboo to the Windows AD:
   <bamboo-home>/xml-data/configuration/atlassian-user.xml, atlassian-user-custom.xml

   <atlassian-user>
       <repositories>
           <!-- LDAP repository -->
           <ldap key="ldapRepository" name="myLdapRepository" cache="true">
   			<host>thanos.atlassian.local</host>
   			<port>636</port>
   
   			<securityPrincipal>CN=admin.user,CN=Users,DC=atlassian,DC=local</securityPrincipal>
   			<securityCredential>admin.password</securityCredential>
   			<securityProtocol>ssl</securityProtocol>
   			<securityAuthentication>simple</securityAuthentication>
   			<baseContext>DC=atlassian,DC=local</baseContext>
   
   			<baseUserNamespace>OU=users,OU=ps8102,DC=atlassian,DC=local</baseUserNamespace>
   			<userSearchAllDepths>true</userSearchAllDepths>
   			<userSearchFilter>(&amp;(objectCategory=Person)(sAMAccountName=*))</userSearchFilter>
   			<usernameAttribute>sAMAccountName</usernameAttribute>
   			<firstnameAttribute>givenName</firstnameAttribute>
   			<surnameAttribute>sn</surnameAttribute>
   			<emailAttribute>mail</emailAttribute>
   
   			<baseGroupNamespace>OU=groups,OU=ps8102,DC=atlassian,DC=local</baseGroupNamespace>
   			<groupSearchAllDepths>true</groupSearchAllDepths>
   			<groupSearchFilter>(objectClass=group)</groupSearchFilter>
   			<groupnameAttribute>cn</groupnameAttribute>
   			<membershipAttribute>member</membershipAttribute>
           </ldap>
           <!-- Default bamboo user repository -->
           <hibernate name="Hibernate Repository" key="hibernateRepository" description="Hibernate Repository" cache="true"/>
       </repositories>
   </atlassian-user>
   

3. search for users by hitting http://localhost:8085/admin/user/viewUsers.action?usernameTerm=&fullnameTerm=&emailTerm=&startIndex=990 in the web browser.
   As a result, Bamboo lists the users up until 1000.

Expected Results

• Bamboo should paginate results over MaxPageSize

Actual Results

• Bamboo displays only the amount records set up in MaxPageSize

Workaround

1. Increase MaxPageSize in Active Directory
   • review and update the MaxPageSize in Windows AD. Followed this documentation (https://support.microsoft.com/en-us/kb/315071)
     
   • reconnect Bamboo with LDAP by selecting Custom user repository under Bamboo administration >> Security >> User repositories
   • search for users by hitting http://localhost:8085/admin/user/viewUsers.action?usernameTerm=&fullnameTerm=&emailTerm=&startIndex=1190 in the web browser.
     As a result, Bamboo listed the users up until ~1200.
2. Connect LDAP to Crowd/JIRA and connect this with Bamboo instead
