In /etc/cups/cupsd.conf, I have the following configurations:
Deny From All
Allow From 127.0.0.1
User 'peter' is a member of the group lpadmin.
However, when I tried to login with userid 'peter' and his password, the authentication window vanishes and reappears (authentication fails?).
What do I need to configure to get the authentication successful?
Btw, what does 'User' in 'AuthClass User' means?
Thanks in advance !
