openssh bugs - Jan 2004 - [Bug 796] sshd should restore previous authdb setting

http://bugzilla.mindrot.org/show_bug.cgi?id=796

           Summary: sshd should restore previous authdb setting
           Product: Portable OpenSSH
           Version: -current
          Platform: PPC
        OS/Version: AIX
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: dtucker at zip.com.au


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.
