[Bug]: Runas doesn't works with domain users in 3006.14

[piterpunk]

What happened?

Using cmd.script and cmd.run on Salt 3006.14 doesn´t works with domain users, always returning:

Invalid user: DOMAIN\user

That happens because #67922 uses user.info to validate the user and it doesn't return any information for domain users.

Type of salt install

Official exe

Major version

3006.x
