AD autenthication - multiple domains

HI

In my organization, we have an AD forest with multiple domains.

I have configured domain authentication on my SuiteCRM (Version 7.9.4), and it work fine, but only for users in the domain indicated in the UserDN parameter.

As suggested in other post, I have configured my LDAP support with:

Server: ldap://[my server name]
Port Number: 389
User DN: CN=Users,DC=[A DOMAIN OF MY FOREST),DC=it
Bind Attribute: userPrincipalName
Login Attribute: sAMAccountName
Auto Create Users: enabled

With this configuration I can connect to Suite only using a simply user name (i.e. “test”, without domain name).

I would like to be able to use the syntax “user@[domain name]” or “[domain name]/user” to connect users from all the domains in my forest, but it does not work.

Is there a way to configure SuiteCRM to enable users from different domains in my AD forest?

Thanks

Hello, could you guide me on where you can see how you can configure the ldap connection for multiple domains ?
