Dynamics AX , should login with Domain user and we will able to login Dynamics AX client side only with that user which will install application first time ,( we can enter the other users as well) but that need to open Application and set user Group and role base security etc
Now the application is installed with other user and I am not a part of user group now, so on data base in which table and what need to update for login.
The reason to know this if any user try to login other machine,(as we have lots of local VMs for test work), they are not able to open application. And they re-install application which is time taking work.
In Dynamics 5.0 I use to update SID for this particular thing,
