This is a very old limitation that is no longer a problem for quite a while. AFAIR starting AIX5.3 AIX has a decent PAM stack and one can use pam_ldap and nss_ldap with it. 5.2 does not have proper capabilities. What version do you use? The limitations you are concerned are really dictated by the capabilities of the OS and client software. AFAIK nss_ldap has no limit on number of the users in a group. IPA assumes that there are no such limitations and allows any number of users in a group. > If anyone has some past experience with AIX, feel free to share with me > > I am really interested to ear about it > > Thank you! > > Sylvain Angers > > 2012/1/5 Dmitri Pal <d...@redhat.com <mailto:d...@redhat.com>> > > On 01/05/2012 04:20 PM, Sylvain Angers wrote: >> Hello >> >> We have a mixed environment of AIX, and linux servers >> All our user accounts are still set locally - no NIS, and we do >> not have unique uid/gid toward our hosts!!! >> I am evaluating the possibility of using Redhat >> Identity management in our environment >> I have to figure out what AIX will be able to support - we would >> at least want to be able to limit who could access what on aix >> so if you have dealt with AIX, let me knows >> >> but here my main question >> >> My question is how do I deal with our current local users? > > This is a tough one...
