You may have noticed that when deploying the WI on a Webserver, the following error may be displayed when specifying the AR server’s FQDN containing a hyphen (e.g. AR_server.contoso.local-ad):
The computer name is incorrect. Supply the fully qualified domain name of the desired computer. Example: computer.domain.com”
This is a Product defect (255869), as the Product is hard-code to run a syntax check using REGEX.
1) Deploy an instance of the AR administration service on the same host as the one you are getting the error above on;
2) Navigate to:
C:\Program Files\One Identity\Active Roles\7.4\Web\Public\xml
3) Locate and edit the Settings.xml file;
4) Make sure to include the external service’s FQDN using the EDMServiceName parameter, e.g:
5) Reset IIS;
6) Uninstall the local AR administration service instance deployed in step 1).
This will be fixed on a future release of the product. Please refer to this article for updates or contact support referencing the defect ID 255869.
