I have installed pam LDAP authentication successfully using RedHat Linux 7.0. I am using the iPlanet directory server 4.12. Authentication and primary group works fine. I can add my own users and groups using the iPlanet interface and it seems to work fine. What doesn't seem to work though is supplementary groups. I just can't seem to get my users to belong to any group besides their primary group. When I do an "id", they only belong to one group. I've tried to access files with only group permissions to which the particular user is a member of (to prove whether it is really true that they don't belong to the group even though I've populated the appropriate information in the LDAP database) but they are definitely not members. Does anyone have any ideas on what I might be doing wrong or what I need to do in addition. Or should it just work out of the box? (I hope not because I'm pretty sure that's how I've set it up).
