Active Directory groups w/ members from multiple domains

L1 Bithead

I'm using AD groups for some security policies and am expanding to use other domains in our company. While I can add users from another domain into an AD group, the PA only shows me the users in the same domain as the group.  For example:

Domain 1: DC=first,DC=com

User 1: CN=idone,OU=users,DC=first,DC=com

Group: CN=cars,OU=groups,DC=first,DC=com


Domain 2: DC=second,DC=com

User 2: CN=idtwo,OU=funnyguys,DC=second,DC=com

 

The domains, first.com and second.com, have a trust relationship and therefore I can add users from second.com into groups in first.com. However, when I do a show user group name "CN=cars,OU=groups,DC=first,DC=com" I only see first.com\idone.


If I look at the CN=cars,OU=groups,DC=first,DC=com directly in AD, user idtwo is in the member list but as a SID.

 

Is there any way to translate FSP (Foreign Security Principals) into usable \ recognizable usernames?

Hi @TomYoung. Thanks for the links as I had not seen them yet! It turns out they don't help me in my situation.  I'm already at the root of each of the two domains, each their own forest, with the only connection being a trust relationship.

Tried to see if group mapping could be done via SAML connection to Entra ID but appears to be LDAP only, at least in PAN-OS 10.2. Investigation continues!
