Ok, maybe i have to explain it more clearly as it was confusing:
in order to get the user list attribute for an ldap group in AIX , you use
some .map files, which map the ldap attributes to the AIX attributes. For
the 2307schema, to get the user list of a group you have to map the
*attribute to the _memberuid_ ldap attribute. For compat tree, in the file
ipagroup.map i've mapped the AIX _users_ attribute to the _memberuid_
ipa/ldap attribute and therefore i have the list of the users for that
particular group. Having the user list which are members to a group
translates to having the group list of the users (if we invert the logic).
Does that make more sense now ?

Actually the compat tree was the default one configured by the ldap client,
but checking the ldap structure seemed more logical to use the default ipa
ldap tree which is used as well for Linux. Moreover i did not understood
what is exactly the purpose of the compat tree and i was quite confused .
Apart from that i missed some krb* related attributes for the user, but
probably i have to re-evaluate that and use compat tree for both users and
groups, if that's what it was designed for.
