Dear Support

I want to configure claim based authentication of MS dynamics CRM with ADFS.

Enviornment -WS2012 R2 with DC and CRM and SQL installed

Client machine -WS2008 with ADFS in same domain

IF trying to login Dynamics,it is redirecting ADFS URL and after authentication I am receiving error:-

An error has occurred.

Try this action again. If the problem continues, check the Microsoft Dynamics CRM Community for solutions or contact your organization's Microsoft Dynamics CRM Administrator. Finally, you can contact Microsoft Support.

Under EIZOAD-w3wp(296#5E415CD4)-CRMWeb-20180710-1.log - found error

Crm Exception: Message: Expected non-empty string., ErrorCode: -2147220989, InnerException: System.ArgumentException: Expected non-empty string.

Under EIZOAD-Microsoft.Crm.Sandbox.HostService-bin-20180710-1.log- found error

>Crm Exception: Message: Access Denied. Reference number for administrators or support: #BFBCA0A9, ErrorCode: -2147187707

Now ,i want to know what i am missing all over.

We can take remote session ,if you want to see configuration.

Did you register any CRM assemblies in the GAC?

Also the CRM AppPool User - is it running under Network Service or an AD User account? Does it have enough privileges on the machine where CRM is installed?

RE: Dynamics CRM is not opening showing error An error has occurred.

Lets forget ADFS and claim based authentication for now,

Normally if i am trying to login administrator on CRM,It shows

An error has occurred.

Try this action again. If the problem continues, check the Microsoft Dynamics 365 Community for solutions or contact your organization's Microsoft Dynamics 365 Administrator. Finally, you can contact Microsoft Support.

Again,I created anant user in AD and tried login ,It shows

No Microsoft Dynamics 365 user exists with the specified domain name and user ID

A Microsoft Dynamics 365 user record does not exist with the specified domain name and user ID.

Both administrator and anant are in deployment administrator,whereas member of four CRM default group ,has permission on CRM apppool SIte in IIS.

I am not understanding after successful installation why these issues occuring?any help please.

I can provide test environment remote session if required.

As Radu Chiribelea suggested ,I updated CRM2016-Server-KB4046795-ENU-Amd64 too ,but no luck!!!

I think this looks like an old bug.

Please install the latest Update Rollup and see if this fixes your issue.
