Due to the way Unix stores user information in /etc/passwd and /etc/group + this inevitably leads to inefficiencies. One important question a user needs to know is the list of groups he + is member of. The plain UNIX model involves a complete enumeration of the file /etc/group and its NSS + counterparts in LDAP. UNIX has optimized functions to enumerate group membership.

It further assumes that the Samba auxiliary object classes are + stored together with the POSIX data in the same LDAP object. If these assumptions are met, + yes can be activated and Samba can bypass the + NSS system to query user group memberships. Optimized LDAP queries can greatly speed up domain logon and + administration tasks. Depending on the size of the LDAP database a factor of 100 or more for common queries + is easily achieved. + + + +no + -- cgit
