i'm talking about creating a user in one database and this user be created in many databases (in the same server)

i'm trying with symbolic links in data directory, but sure i have some problems that i need same server version (ok no problem) and flush tables in all servers after add an user

i don't know if i could do a two replications since it's like a master-master storage when one database add a user all databases need that information

any idea?
