App Control: AD Logins Fail When Active Directory OUs Have Special Characters

[#1]

Environment

• App Control Server: 8.9.x
• Microsoft Active Directory: All Supported Versions

Symptoms

• After Server Upgrade to 8.9.x AD user accounts can not log in to App Control Console
• Recreating the User Role Mappings with the relevant Active Directory Folder/Group does not resolve.
• AppControlAD-TIMESTAMP.log results show the EscapeFilter including the Hex code for a special character, such as a slash:

  EscapeFilter - EscapeFilter(CN=User\5c, Name....

Cause

Active Directory Organizational Units have one or more of the following characters:

\/:*?<>|~:!@#$%^&'(){}

Resolution

Upgrade to 8.10 where this issue has been resolved (EP-17684\EA-22686)

As a workaround the Shepherd Config, AllowADScript could be used to force the "old logic" for Active Directory using vbscript. This should be reverted after upgrading to 8.10.

1. Navigate to https://AppControlServer/shepherd_config.php
2. Select the property AllowADScript
3. Change the value to true.
4. Restart the App Control Server & Reporter services.
5. Verify the AD accounts are able to login correctly.

Additional Notes

• When AllowADScript is set to true Active Directory logging will be included in ServerLog-TIMESTAMP.bt9 and the EscapeFilter will log the special characters similar to:

  EscapeFilter - EscapeFilter(CN=User\, Name....
