Can someone explain what is going on here... After installing ML7.2, I created a user, the uid alloted was 501. After that I added some more users with uid's 502, 503 etc. The I deleted the user whose uid was 501. When i tried to add the same login name at a later time, it said that the login name looked like a group name and refused to let me add that. However after quitting drakuser after deleting that user (501), i restarted drakuser and it allowed me to add a user with the same login name, however the uid assigned to that guy was 507. But the I am unable to login as this guy. I cannot understand why it won't let me log on as this guy, even tho it shows up in the login GUI. My questions are: (1) Since UIDs are assigned in increasing order, will I ever have access to UID 501 again? Or for that matter old UIDs that no longer have a user?? (2) Why am I unable to access the an account that seems to exist? Thanks in advance... Surya
