HELP !!! Authentication Error after migrating from CRM 2011 to CRM 2016 RRS feed

  • Question

  • Hi,

    We have migrated our system from Dynamics CRM 2011 to CRM 2016 recently following the Guide provided and resolved all the conflicts/issue. But recently we observed on strange error occurring while logging a particular user with a security role(other than system administrator) and CAL Information as Access Mode: Administrator and License Type: Administrator.

    Its used work properly when the system was in CRM 2011. But now we are facing this issue.

    If the CAL information for the user has been changed to Access Mode: Read-Write and License Type: Basic, the user was able to login successfully. But we require to set them as Access Mode: Administrator and License Type: Administrator.

    After digging more into the error, we observer in the event viewer an information while logging as below:

  • As far as I know there is no license type or access mode called  'Administrator' available in CRM 2016. We have our common users set to to Access Mode: Read-Write and License Type: Basic, and our Administrators and service account to Access Mode: Read-Write and License Type: Professional.

    With our migration from CRM 2011 to CRM 2016 we exported all users from CRM 2011 and imported them into CRM 2016. If a user was not able to logon to the system I resolved this by replacing his user name in CRM 2016 with a empty AD account (like: domainname\usernamefix) . Saved the user, and then replaced the username with the original username. And saved it again.

    This worked in all cases.
