Hi, A user has an issue where they are prompted for a password for the lpadmin. Now this user has a mobile home account and there are networked printers. No managed printers or queues. I know this changed in 10.5.7 and this support doc on Apple.com http://support.apple.com/kb/HT3511 says to add the user to the group. However this is no good as I want to stop it happening. The user should never be prompted for a password regarding printers. Has any one else had this issue? I believe it is down to the fact that the user switches between networks. The printer queue becomes paused and then to resume the printer it is prompting for a user/password that is a member of the lpadmin group.
