      Problem

      During Azure AD synchronization, some returned messages regarding group removals might not be parsed correctly, resulting in the synchronization failing with an exception like:

      2017-12-03 13:51:02,527 Caesium-2-3 ERROR [atlassian.crowd.directory.DbCachingDirectoryPoller] Error occurred while refreshing the cache for directory [ 131074 ].

      Suspected cause

      1. Azure AD is returning soft-deleted Groups where the JSON group object is missing the displayName field
        • Azure AD only purges soft-deleted Group Information after 30 days

      Workaround

      1. In some cases disabling incremental synchronization, or recreating the affected directory in Crowd might alleviate this.
      2. Permanently purge the soft-deleted group information from Azure Active Directory prior to the 30 days by following the workaround described in Crowd Synchronisation with Azure AD fails with "java.lang.IllegalArgumentException: name argument cannot be null or blank" KB article
