User login issue for Custom Roles in MS CRM

I hope this blog should resolve your Issues. The culprit is that the role assigned to user. User, who logs into MSCRM for the first time should have the "Write” permission on the entity "User Settings" (check under the "Business Management" tab in the role).

Once you login the first time with that permission, CRM does some backend "house-keeping" tasks that will take care of your issue with login.


Thanks to Shaak :) who pointed out this in a Discussion Forum.
