Master Password Server Process
The Master Password Server process provides two major functions: 
•
Permitting a master user, with a corresponding “master password,” to perform 
operations on the mailboxes of other users
•
Validating user passwords in connection with MS Bind and Register-MS requests 
from remote and local user agents
Once a master user is defined, either the master password or the APPL password can be 
used for access to a mailbox, and the master user can perform any operation the mailbox 
owner could perform, except to change the password. The master user can also bind to 
its own mailbox, using its O/R name (for instance, to change the master password). For 
security reasons, there are options to prohibit the master user from binding or registering 
under its own name. 
Figure 7-3. Master Password Server—Basic Configuration 
Note. If the master user performs any fetch or list operations on another user's mailbox, then 
the entry-status of the messages examined will be updated even though the owner of the 
mailbox has not examined the messages.
