Access to the CCSM repository is controlled through membership in Unix groups and the LockDir feature of CVS-1.11.
The UNIX groups are available only on goldhill (or CGD suns), and are used strictly for access to the repository. (Note: "ccsmr" stands for CCSM repository). In addition the following individuals have access to all groups: tcraig, southern, ccsm, csm, erik, and mvertens. These individuals are responsible for tagging the entire system or maintaining CVS access.

they don't have permission to access? After the log information is entered
