Hi Mike, You are right, I am not sure why that is. But I did remove the pwcheck from common-password just to check if that was indeed the issue. It isn't, though the errors on pwcheck and libcrack were gone at that time. I have ran rpm -V on pam-modules and cracklib and found that the cracklib module might be off. So that could explain that.
Since I am confined to a 3270 console at this time I don't have all the functionality available I would like. So my first objective is to get ssh login possible again and then look what needs to be done next.

Why would PAM be unable to open that? Do you have a similar system where SSH logins are working? If so can you compare all the files in /etc/pam.d. If any of them have changed, back them up then copy them from the system that is working? Just a thought ... -Mike On Thu, May 26, 2016 at 5:06 AM, van Sleeuwen, Berry < [email protected]> wrote: > Hi All, > > I try to login to a SLES10 linux guest.
