Authentication for multiple AD domains

Hello,

Currently we have MS AD datasource as UME for all our internal portal users. We also have spnego setup for authentication for our EP 7.0 The user path and group path is of the form dc=dom1 dc=company dc=domain dc=com.

Now we are planning to add additional domains to authenticate users .

Will the configuration differ if they are maintained on a different ldap server altogether or when only the user and group paths are different for the new domains as shown below? The user path and group path is of the form dc=dom2,dc=company,dc=domain,dc=com and

dc=dom3,dc=company,dc=domain,dc=com.

It seems that we have to change the datasource file for the additional ldap scenario.But are both of these the same,Would appreciate if someone could clarify this.
