It's probably not a good idea to duplicate entries (same user) in LDAP & /etc/passwd and can lead to unpredictable behavior. There's nothing that prevents you from adding LDAP users into /etc/group and in a few cases, I do this (primarily for database files and backup). Respect the division between /etc/passwd (typically system users and groups) and LDAP (active users and groups). Providing you have properly configured pam modules (again, not an OpenLDAP discussion), there shouldn't be a problem with LDAP users & groups in /etc/sudoers. Craig
