I have strange issues on my test Dynamics CRM on-premises deployment.
Installation is Full server on Amazon EC2 instance with AWS Directory Services as Domain controller.
Setup has been completed using this guide:https://www.interactivewebs.com/blog/index.php/crm/how-to-set-up-microsoft-crm-2016-ifd-on-windows-2012-r2-server/
Problem is that after external login ADFS doesn't redirect me to the CRM. ADFS authenticates the account (record in the Event log and it shows error for the invalid password). But then it redirects me back to the ADFS page instead of the CRM.
Event log shows 4 records for the each login attempt. 1. Audit success for my acount 2. Audit success for the ADFS service account 3. and 4. Audit failure for the ADFS service account (NULL SID)
Did all checks - service permissions to the Certificate, firewall, ports - nothing helps.
Even tried to change external address from the suggested "auth" subdomain to the "org" - still nothing.
Any suggestions would be greatly appreciated.
