I have installed RHEL 6.2 and configured for using LDAP with the setup utility and I can login.
What is stange is that only three LDAP groups are recognized per user. It is different groups, even for users that belong to the same groups. The gid range id from 500 to 30000+.
The LDAP server is openldap with SLES using it's standard schema.
I have not to my knowledge configured any limitations or filters, so why does it pick only three arbitrary groups?
