Use hide_maintuser_pwd to configure password protection for the maintenance user and restrict maintenance user access to Replication Server.
create connection to data_server.database set error class [to] error_class set function string class [to] function_class set username [to] user [set password [to] passwd] set hide_maintuser_pwd to ‘{on | off}’ ... go
alter connection to data_server.database set hide_maintuser_pwd to ‘{on | off}’ go
configure replication server set hide_maintuser_pwd to ‘{on | off}’ go
The default is off.
If multiple connections to the same or a different database controlled by Replication Server share the same maintenance user, Replication Server alters the maintenance user password for all the connections if you set hide_maintuser_pwd on.
