You can have replication going frequesntly on name.nsf.  

Look into muti server session authentication http://www.ibm.com/support/knowledgecenter/SSKTMJ_9.0.1/admin/conf_multiserversessionbasedauthenticationsinglesignon_t.html

when you set this up with a along with a modified login page on the other servers you can then force the user over to the server that you changed the internet password and then woul direct them back to the database that they are trying to access

If you are able to cluster the three servers, then when the user changes the internet password, it will automatically replicate over to all servers in the cluster.

That's the problem. Right now I don't wanna force sync names.nsf, because of different userID, etc. I woud like only to sync passwords. So when someone change password through Notes, iNotes pass will changed (it is was set), and then I want to snyc that password on other two servers in same Domino domain.
