AIX 5.3a won't authenticate my users from a Linux-based NIS server
We have an AIX 5.3a installation running on our AS/400. Our NIS servers is a Linux CentOS 6.x server. The AIX seems to be reading the NIS maps properly, ypcat on the password file works fine. However, the machine will not allow NIS users to log in. When we try, we get log messages like this:
Nov 16 08:55:33 alaix53a auth|security:info sshd: Failed password for testman from 172.25.13.17 port 42466 ssh2
Nov 16 08:55:33 alaix53a auth|security:info syslog: ssh: failed login attempt for testman from willow.hq.aldon.com
Not very helpful.
An lsuser of the above reveals the following (in part):Testman
This user is only in NIS, it has not been set up locally, but it seems to have the proper permissions to log in. It does have a home directory available, and simply su'ing to the user works fine.
