Hi, I have a curious problem where a few (important) users cannot log into the Red Hat Enterprise Server 4 update 4 systems. However, most users (including myself) can log in. These users can log in fine to ldap'd RHES3 Update 6 systems. The FDS logs indicate a normal fetch of the user's attributes with no errors. The /var/log/secure on Red Hat 4 simply says sshd[8898]: Failed password for <username> from <hex>... Yet they can log into other LDAP based systems, including a few other RHE4 systems, that all go back to the same FDS. I have deleted their accounts and recreated them, which usually fixes strange problems like this, but no luck. Some accounts are old (date back to FDS 7.1) and others are new. I examined the DS attributes for these users, and the only difference I could find was the "Object class" attribute was missing the "account" value. So, I added it, but to no avail. I compared /etc/pam.d/system-auth and they are essentially identical between RHES3 and 4 systems. /var/log/secure also has a "error" Could not get shadow information for <username>" but that happens on all users. It seems to be a soft error, but I would like to get rid of it. Can anyone give me a clue where to look? Thanks! Ken
