Openssh login behavior changes or fails after SLES 10 SP4 is installed

This document (7009233) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 10 Service Pack 4


SLES 10 has been updated to SP4
SSH and SFTP authentication now fails, or at least changes in it's behavior.
SSH stops working after SP4


After updating to SP4, the pam file for sshd (/etc/pam.d/sshd) will have been replaced and the new file will contain a new configuration.  This new default file addresses minor security concerns and is needed with the new openssh 5.x package provided in SP4.  If any customizations had been done to this file previously, they will no longer be in effect.
The previous /etc/pam.d/sshd file will be saved as /etc/pam.d/sshd.rpmsave.  However, for those who need to re-customize their file in order to regain certain functionality, it may not be appropriate to simply copy the old file back into place.  Pam files affect authentication security, so any customizations should be carefully considered before being implemented.  Carefully consider the contents of the old and new file to determine whether / how they may need to be merged.
