Incorrect Login Name Bombs out

[Steve21]

Morning Guys,

 

Not sure if there's an easy fix or if I did something wrong with this but seems if people try to log in and put an incorrect user name it bombs out:

(also if you put the domain name during login as guessing that's counted as a "wrong username")

anyone got a clue why it's doing this

Guessing it's trying to pull "something" from data it pulls off a user and isn't returning the data so erroring if it's missing a check somewhere Just hoped it might be something silly I did, as was looking to roll it out over Summer and our users can't ever type stuff right haha

We find it helps scare them into typing properly

Also makes it nice and easy for external "people" to test if certain user accounts exist on your network though
