I would appreciate some suggestions. paul -------------- next part

recently we upgraded a bunch of systems to OpenSSH-3.6.1p2. alot of our systems have automated logins for backups or systems checks with ssh-keys, but (i think) as a result of the Openwall/Solar Designer patch, pam_tally is incrementing off the scales. pam_tally is tallying failed logins for keyed-only accounts: attempts are made to authenticate those accounts via password authentication before

All, (Sorry if this is a repost, I tried without being a subscriber and saw nothing after a day, so I'm trying again after subscribing). I think this is a problem with how sshd uses PAM. Basic scenario: - sshd is configured to use PAM with pam_tally2 - Multiple clients try connecting within a small time frame - Some of the clients fail to authenticate The problem is that the tally is

Dear FreeBsd gurus, I have a problem concerning users password and authentication policies. The goal is 1)make freebsd to lock users after 3 unsuccessful login attempts, 2)force users to change their passwords every 90 days I've done such changes in Linux distros, with various PAM modules.But in Freebsd it seems that i need to use login.conf file.

Hello all, At this moment I am running a samba-ldap-pdc. This works really good. But what worries me is the following thing: user accounts never get locked. This is a problem cause anyone can guess or use bruteforce to enter password. Is there a solution/workaround for this?

The old server was just the way we needed it.....but now that the new server has gone live it appears we
