I don't use LDAP and so am not familliar with CUPS configuration to
using LDAP.

If I understand correctly, when using the "AuthType Basic", CUPS will
use the OS authentication system; ie, /etc/group for example.

Perhaps someone with LDAP and CUPS implementation can provide a better
understanding.
