The Local Registry
The local registry, which resides in the dcelocal/var/security directory on each local machine, contains information about the machine's most recent users and the date and time that they last logged in. If a security server is not available for network login, the authentication service attempts to obtain the information that is required for a local login from the local registry.
When a security server is running on the network, the authentication service automatically creates a local registry the first time anyone logs into DCE from the machine. Thereafter, it updates the local registry each time anyone logs into DCE from the machine. You can edit the local registry by using the rgy_edit command with the -l flag. Note that the dcecp command does not access the local registry.
(See Handling Network Reconfigurations for an example of how to use the rgy_edit command to perform this task.)
