Hi Thomas, Thanks for the replies~! Really appreciate it.
To answer your questions: For the group DN, I was watching the logs, and while yes, I could have put the full dn in there, it does a check to see if it can find it with the group dn alone and if it can’t find it, it then tries to find it with the base dn and then the group dn as a filter. So that’s why I just put the cn=mygroup in the group name. My group ldif looks like: This is the query i run, it’s the same query xwiki is executing when trying to if I’m a member of the group: ldapsearch -x -h od.mycompany.com -s sub -b dc=mycompany,dc=com cn=mygroup attributes objectClass uid memberUid # extended LDIF # # LDAPv3 # base <dc=mycompany,dc=com> with scope subtree # filter: cn=mygroup # requesting: attributes objectClass uid memberUid # # mygroup, groups, mycompany.com dn: cn=mygroup,cn=groups,dc=mycompany,dc=com objectClass: posixGroup objectClass: mycompany-group objectClass: extensibleObject objectClass: top memberUid: member1 memberUid: member2 memberUid: member3 memberUid: member4 etc…. Finally, I read the jira bug and I’m not totally sure (from the description) if that’s the issue I’m seeing. You said that an LDAP subgroup is listed as UID it’s not expanded. But the issue I’m running into isn’t related to subgroups, it’s that when there are multiple memberUid’s in the group, that logic isn’t adding all of them into the member map object, thus it incorrectly determines that a person isn’t in a group, if they’re not the first in the list. Please correct me if I’m seeing it wrong. And doubly finally, if I’m wrong and the issue is fixed (which would awesome), when can I get the fix? It’s really holding up using xwiki on a broader scale because I can’t get it integrated with our LDAP.
