Occurs when using *Read Only, with Local Groups* or *Read/Write* LDAP Permissions in your directory connector.
Cause
This issue is caused by there being multiple groups in your external directory with the same name (could be different cases name).
Solution
Resolution
If you want to use some of your groups then you must configure your Group Object Filter in the Group Schema Settings of your connector to not include the groups causing issues. Example:
1(objectCategory=Group)&(!(cn=Users))If you want to use groups only in JIRA, and exclude all of the groups in your directory then you can specify a bogus objectCategory. Example:
1(objectCategory=FKSLDJFHNSDUIEWIYFHBYCNWNCEWNFIYWFBLYCINEW)ℹ️ There is an open bug to improve the handling of this. All users hitting this issue are encouraged to vote and comment on it. JRASERVER-28484 - Improve handling of duplicate group
