Thanks. I'm stuck though.
IBMs insistence on doing everything Not Unix in AIX is frustrating my
1) they don't use straight up PAM. They have some older version they
include with the OS.
2) their version has very few modules that come with it. It does, however,
but does not include pam_krb5.
Here's the list:
pam_aix pam_allowroot pam_mkuserhome pam_prohibit
pam_allow pam_ckfile pam_permission pam_rhosts_auth
That's a far cry from the 69 or so pam modules I see on Linux boxes.
Before I can move on I have to get pam_krb5 to build for AIX and that's
proving to be very difficult.
I'm hoping the pam_hbac thing will pan out.
I'm about ready to just yank Kerberos from the AIX machines and fall back
to local authentication.
The actual AIX admins seem to have no interest in helping me, so they can
reap what they
sow with their inaction and have to manage individual users on individual
