I've set up phabricator and added several users. I noticed that I can change a user's real name or username, but I am unable to change their email address. Is there some reason why this is not exposed to admins? Is there a server setting that allows admins to change email addresses.
Administrators can not change email addresses because it would let them change a user's email address to their own, reset the user's password, and then log in as the user. Administrators are not all-powerful in Phabricator's permission model, and can not compromise accounts, act as other users, or violate policies.
If you need to change an address because you made a mistake when creating a new account, you can delete the account and recreate it.
You need to update the mysql database. In the phabricator_user db alter your email address in the user_email table. Administrators may not be all-powerful, but DBAs are.
As bridiver writes, you need to change the address directly in the database. For that, you can use a helper Phabricator script to connect to the database:
$ phabricator/bin/storage shell
[...]
mysql> use phabricator_user;
Database changed
mysql> update user_email set address='newaddress@example.com' where address='oldaddress@example.com';
Query OK, 1 row affected (0.05 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> quit
It might be new, but they have a way now. I'll just list it here in case anyone has the same question later.
Log in to the server, where you have your Phabricator install, and use ./bin/accountadmin. That will let you change or add accounts at will. If you just want to look at the user, you can look in the phabricator_user database and check the user table or the user_profile table.
