The 3.7 versions of Openssh will refuse to authenticate via password (didn't try keys) for the ssh.com and Putty clients IF the server is using ldap authentication. I used the 3.6.1_p2-r3 ebuild and applied the patch from the openssh site and all is well. I'll be submitting the bug to the openssh bugzilla as soon as I get a password... Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 17895 [details] DEBUG3 output This is a dump from my logs of the failed login attempt from windows clients...
New OpenSSH version now is also incompatible when using PAM and PasswordAuthentication off with old ssh UNIX clients and older version of putty. Note that when using PAM now setting PasswordAuthentication off is required, otherwise users can bypass PAM authentication... :(
http://bugzilla.mindrot.org/show_bug.cgi?id=669 discuss this issue. Does it work if you upgrade the client?
Nope... same problem occurs with the latest putty and ssh.com clients... I haven't had any problems with the windows clients connecting to a server using the "normal" passwd/shadow auth, which I find to be quite odd.

This is out of my hand. Closing becuse upstream closed bug.
