Description Darren Tucker 2004-01-25 17:53:11 AEDT 
Currently on AIX, sshd does something like this:
    setauthdb([whatever]);
    aix_auth_functions();
    [ much other stuff ]
    setpcred();

In some cases, (eg if the password registry is NIS) the setpcred call fails. 
(This is possibly a bug in the AIX NIS module, this behaviour has been reported
on AIX 5.1 ML4 and AIX 5.2 ML2.)

sshd should probably restore the previous authdb setting after calling the AIX
auth functions.

Also reported as not working: AIX 5.1 ML5 with NIS and AFS password registries.
