Symptoms and conditions:

1. User Sync module is used for syncing Azure users
2. Latest sync blocked all Azure users

Cause:

Client secret generated for the Claromentis app in Azure has expired which causes connection error between Intranet and Azure during the sync.

Immediate resolution

Support team to

• take the screenshot of the User Sync admin panel which includes the security groups in it. Ignore this step if the ‘Security groups’ is already blank
• Communicate to the customer that they need to update the Secret ID in Azure and copy it to User sync
  • In Azure it is found in App registration > [App Name] > Manage > Certificates & Secrets > New client secret
• Customer provides the Secret ID to Claromentis:
• Custom team then 
  • adds it to User Sync admin panel and 
  • updates the groups, ether from the screenshot or from the recent backup of core.json
  • Runs a sync
• Customer confirms that the issue is fixed

Permanent solution

Custom development team are currently working on the solution which will prevent the negative effects of Client secret expiry.
