Good Afternoon,
I've seen something out there that will synchronize the user lists between servers. I'm racking my brain trying to remember it but in the past, it has been an insecure method. This being said, people have shied away from it. They now have a more secure method which may warrant another look. I haven't tried it yet but there is some information about it on the forums. Do some digging and you'll find it. If I can find it on my computers at home, office, doghouse, etc., I'll post it.
I'm still looking for a flag or something to trigger a password reset. I'm needing something to require a password reset for any user that is on the SME box. Whether the box is being used for SQUID authentication or SAMBA authentication. I don't believe that resetting passwords should fully be an network manager's responsibility. Also, keeping the same dadblame password for eons creates security risks. On the flip side, I'm not for resetting a password every time you come into work either.
Oh well, enough of my rambling. If I find that information, I'll post it.
