EP with SRM - User's management

Hello experts,

We are implementing SRM 5.0 integrated in Enterprise Portal 7.0 (2004s)

I would like to know if it's possible to create users via EP and replicate the user (and it's roles) to SRM. Can it be done via UME?

I am not really sure if this can be done this way or the other way around: create the users in SRM and replicate them to EP? Can this be done automatically?

How about massive user creation under this scenario?

Let me know how you've dealt with this

Thanks!

Regards,

Gilberto Gallardo
