login "you are attempting to create a user with a domain logon that does not exist" RRS feed

  • Question

  • I sporadically get the error "you are attempting to create a user with a domain logon that does not exist" when I log in to my development environment. When it enters this state there appears to be nothing I can do to resolve the error apart from walk away from it for a hour or two and then try again when it might work.

    A complete reboot of all servers has no effect, IISRESET has no effect, this is an account which usually works so it most definitely exists and the error occurs when I try to login so I am not trying to create any user.

    Why is CRM lying to me? what is the real error and how on earth can it be made to work again?

  • Hi,

    This kind of probelm can happen if the user account's Obejct SID is different in table [MSCRM_CONFIG].[dbo].[SystemUserAuthentication].

    1.Get the AuthInfo value for the user from the table [MSCRM_CONFIG].[dbo].[SystemUserAuthentication]
    2.Get Object Sid of the user 
    follow the steps mentioned in the blog :
    3.Compare the SIDs

    Refer the below url for more details :

  • That would make sense if the error occurred on adding a new user but it doesn't. The error affects all users, all users were able to log in, CRM spontaneously locks them out and then after a few hours spontaneously lets them all back in again. So unless something was changing the user SIDs, recording the old ones and then putting them all back a couple of hours later that's not the solution. There is some more generic error going on here that is being misinterpreted by CRM.
