Are they still bugged? I remember this from some time ago and have not tried again because I’m playing other chars now that are not high level enough but last talk entry at the wiki page is from October 31th.

At some point in the story you are allowed to use the portals at Fort Trinity to travel to all of the order headquarters. You can travel back but if you leave the area with the portal you need to talk to an npc to get through the door and use the portal. Only the npc of the order you joined will let you pass.
This seems a bug. I even remember having this reported ingame. Hope this will be fixed. Can’t understand why they won’t let me pass – I’m commander of that pact and they don’t need to protect against someone that is allied with them and leaving. I could understand if there was restriction from the other direction against attackers or spies… but not this way.
