Hi Experts,

I have upgraded the Azure AD drive from 5.1.5  to After the upgrade the driver is working fine for the past one week. But today the driver isn't coming up and getting the below error,

I've tried the following method to fix the issue:

  1. Restarted the IDM exchange online service in the remote loader
  2. Restarted the RL instance for AzureAD remote loader
  3. Restarted the RRL server
  4. Removed the cache from the AzureAD driver and restarted it
  5. Restarted the eDirectory
  6. Deleted the zoomdb file for the AzureAD driver in the following path /var/opt/novell/eDirectory/data/dib/dx100036.zoomdb

After doing all the above steps, still the Azure AD driver is on stopped state and not coming up..

We tried to replace the exchange server related dll file in the remote loader server based on this Azure AD readme file -

If we restart the Exchange server we getting No connection to remote loader and if we restart the RL service for Azure AD then we getting the issue related to Exchange online server and vice versa

Could anyone  please help me to fix the issue??

Any help much appreciated!!
