Help with SSH V4.2p1 and netgroups in password file - OSF/1

[Mr.Mike Cross]

Hi
 
I'm using either V3.2 or V4.2p1 depending on the system.
 
Server - OSF/1 V5.1 latest patch kit.
 
If the system has all the accounts in the password file - ssh lets the users login.
 
If the system has "+" at the end of the passwd file, users in the local password file or in NIS can login
 
if I change the /etc/svc.conf to have "passwd=local" and add + at users:x::::: to the passwd file, the users who are local to the passwd file can login, but the users in the netgroup fail to login, just getting access failed and re-prompted for their password.
 
The system works for login/telnet/ftp/rsh/login so I believe that the system is configured correctly, have I missed some configuration option?
 
Any help will be very welcome.
 
Thanks
 
Mike
