Cross-faction trading, mailing and grouping now ignores worldserver.conf settings?

[Arnagest]

My friends and I run a LAN server. To facilitate trade and character leveling, we set the flags in worldserver.conf to allow cross-faction group and guild invites, mail, and chat.

Recently an update was issued that now prevents these cross-faction interactions. This is despite us having them enabled in the worldserver.conf file. Are there any fixes incoming for this, or does anyone have any tips for restoring these features please?

Poking through the discord, apparently those settings (among others) were moved over to the new RBAC system introduced a while back. The wiki goes into the systems finer details, but if you just want to default apply a permission for all players (for similar results as the old config settings) an insert like below should suffice.¹

Adds cross faction chat permission (25) to Sec Lvl Player (195)
INSERT INTO acore_auth.rbac_linked_permissions (id, linkedId) VALUES (195, 25);

Remember to record your changes. Ideally using a commented .sql script, in case you ever need to adjust/revert/reapply/etc.
After making your changes to the db, you can reload rbac on the worldserver to apply them (and reload config, if changes were also made in worldserver.conf).

For reference, below should be all the 'cross faction' permissions from acore_auth.rbac_permissions on my test server atm (AzerothCore rev. 7c87b14+ 2026-09-25 22:18:20 +0000 (master branch))
24. | Two side faction characters on the same account (ALREADY SET BY DEFAULT)
25. | Allow say chat between factions
26. | Allow channel chat between factions
27. | Two side mail interaction
28. | See two side who list
29. | Add friends of other faction
51. | Allow trading between factions

Note: not every cross faction setting from worldserver.conf were moved to RBAC. The remaining options should still be adjusted in the config. If adjusting there does not work correctly (and rbac_permissions was double checked for new/missed additions) then presumably it's a bug and should be reported in the issue tracker.

Footnotes

1. Would probably be preferable to adjust permissions with the .rbac command or similar, but it seems to currently only allow setting permissions for accounts, and not roles. ↩
