Hello everyone, I’m new to this and are trying to setup a working trust against an AD forrest, I seem to have a working trust but when I try to reference external groups (or users) I get: # ipa group-add-member ad_users_external --external "AD2\Domain Users" [member user]: [member group]: Group name: ad_users_external Description: AD users external map Failed members: member user: member group: AD2\Domain Users: trusted domain object not found ------------------------- Number of members added 0 ------------------------- I enable some logging and last in the mail is the output there from the command above, any suggestions what could cause this? Current version of IPA is 4.5.
