Hello, The uid attribute referenced in 01common.ldif shows as having syntax of. 1.3.6.1.4.1.1466.115.121.1.15 or case insensitive which is what I want. However memberUid referenced in 10rfc2307.ldif shows as having syntax of. 1.3.6.1.4.1.1466.115.121.1.26 or case sensitive which is cramping my style a bit and leading to inconsistencies in the returns of the groups command amongst other things. For example I may have a user uid=joe_doe and he is listed in the posixGroup cn=celtics as memberUid: Joe_Doe and listed in the posixgroup cn=cavs as memberUid: joe_doe. He will only be returned as being a member of cavs and not celtics when I use the groups command. My belief is that this is do to SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 setting for memberUid. Sound about right? I am curious to know if this is configurable? Can I modify the syntax for memberUid to be case insensitive as uid is by switching the SYNTAX from. 1.3.6.1.4.1.1466.115.121.1.26 (case sensitive) to 1.3.6.1.4.1.1466.115.121.1.15 (case INsensitive) ? What are the repercussions on the various groups/users I have already existing in the directory? Will I have to delete and recreate my indexes if I do do this? thx
