Unable to Add User Due to 'Cannot write to read-only GroupManager'
Symptoms
When adding a user, or perhaps adding a user to a group, the following error is thrown:
Cause
java.lang.UnsupportedOperationException: Cannot write to read-only GroupManager [ldapRepository]
at com.atlassian.user.impl.ReadOnlyGroupManager.addMembership(ReadOnlyGroupManager.java:35)
Stack Trace:[hide]
java.lang.UnsupportedOperationException: Cannot write to read-only GroupManager [ldapRepository]
at com.atlassian.user.impl.ReadOnlyGroupManager.addMembership(ReadOnlyGroupManager.java:35)
at com.atlassian.user.impl.cache.CachingGroupManager.addMembership(CachingGroupManager.java:156)
at com.atlassian.user.impl.delegation.DelegatingGroupManager.addMembership(DelegatingGroupManager.java:231)
Cause
There is a group with a duplicate name in the LDAP repository, usually confluence-users or confluence-administrators.
Resolution
Make sure these group names, reserved for internal use, are not in your LDAP repository.
