I have an SCO Open Server running Sendmail, and one of the users received a Mail-Bomb - their mailbox was filled to the point where there wan no HD Space left. I logged in as root, cleared the mailbox, then re-booted. First, the server rebooted seemingly ok, but when I logged in again things seemed very slow. I ran fsck - no problems. I rebooted again - this time when it re-booted, it gave me an error like "su: bin: no user ID" three times, then went directly into maintenance mode with an error message that the security database files were corrupt or missing. They were not missing. I checked permissions - all ok, I restored them (the tcb/files/auth/... files, passwd, group, and shadow). When I rebooted, It still went into maintenance mode with the same error message. If i invoke SCO Admin, it won't let me add or modify any users, saying "cannot access user file". I tried fsck again - still allok, I tried authck - tries to fix users, but cant. I tried tcbck - reports each user in databace but not accessable. I suspect the problem might be that some functionality (as tcl???) might not be operating correctly (maybe because an environment variable isn't set???). I believe that the security database is ok. Sorry for the long post ...any ideas?
