The three potential reasons for the failure of a new user not being provisioned to Netskope an hour after being added to the domain could be:

B. The server that the Directory Importer is installed on is unable to reach Netskope’s add-on endpoint: If the server cannot connect to Netskope’s endpoint, it cannot sync the user data. This could be due to network issues, incorrect configuration, or firewall restrictions1.

C. The user is not a member of the group specified as a filter: The Directory Importer may be configured to import users from specific groups only. If the new user is not a member of these groups, they will not be imported into Netskope1.

E. The default collection interval is 180 minutes, therefore a sync may not have run yet: The Directory Importer may be scheduled to sync every 180 minutes. If only an hour has passed, the sync process might not have occurred yet, and the user would not be provisioned until the next sync interval1.
