Showing incorrect username and password while adding a user in RTC 2015.

Hi all,

An error like "username and password is incorrect " will give a picture of the username and the password is not matching. But what if it doesn't................??

Today I had an error like this while adding user into Dynamics NAV 2015. 

I was looking to get any solution from the internet and it did not work. Finally , I have found an solution from the AD (Active directory) side.

 As I mentioned before the error will not provide an clear view about the solution.

According to above mentioned error while adding new users , I have checked from the local machine
lo gin and the passwords.

Then I turn to check AD login properties and I have found logon name is not set on AD users.

Finally , It was work  !!! The error is about missing user logon names.

However, I  have found some posts that ask about this issue relating to user groups.

But I think this will only work if u get this error when adding a "new user" only.

Thank you.

Regards,
Dinuka.
