[OpenAFS] pam and OpenAFS

[lamont@scriptkiddie.org]

I believe that openssh does getpwnam() and unless you have nss_ldap 
configured or you have the user in /etc/passwd+shadow, or have nss 
configured via some other means, sshd will consider the user 'invalid' and 
fail.  I thought there was a config option that would relax this check, 
but I can't find it...  (I think I'm getting confused with the 
LOCKED_PASSWD_PREFIX feature of sshd there...)
