Hi! I'm interested to syncronize a group of user on 3 different DNN portal istance (3 Databases) but on the same server.
I'm interested that wen a user are linked to a specific role he can be login with the same credential to the other 2 portal, and the same for the other portal.

Hi hope try more clear

Portal A
- Users role: Client of Company A
- Users role: Client of Company B
- Users role: Client of Company C

Portal B
- Users role: Client of Company A
- Users role: Client of Company B
- Users role: Client of Company C

Portal C
- Users role: Client of Company A
- Users role: Client of Company B
- Users role: Client of Company C

If i need i can to be create the same user role on all the 3 portals.
and after If one of my user are linked to the "Users role: Client of Company A" this must to be shared with all other portal and this user can login to the Portal C with they credentials.

Ps. I need the enterprise licence to make this?
Is possible to buy this licence direclty from our website?
thanks

This module can only import/export users and doesn't allow "sharing".
MPUS_X can do sharing but within one dnn instance only.
Of course you can export your users from one portal and import them to other portals.
MMS Pro would be actually the module to export users belonging to a specific role but when importing it can only create new accounts and cannot update existing accounts.
