Hi,It's Debian bug #242236: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=242236
Apparently the pam_ldap's session functions don't actually do anything, and they return a result that confuses SSH and makes it go into a loop, so they can be safely commented out. Not that you shouldn't comment out the account, auth, and password lines to do with pam_ldap, just session.
HTH, Chris
I just had the same problem, and I found out it was due to the pam_ldap module. If you comment out the "session sufficient pam_ldap.so" line it solves the problem. If you're not using pam_ldap it might be a similar problem, try running sshd in verbose mode and see what sort of output you get before and after you kill the out of control process.yes, thats it. but of course i need pam_ldap.so , so is it way to fix it or is it pam/sshd/... bug?
