Unknown Realm

Possible causes for this error message:

  • Problem: The host name is invalid or your security server cannot find it.

    Solution: Verify your realm configuration.

  • Problem: A connection to the host could not be established.

    Solution: Make sure that the host is functioning properly.

  • Problem: There is a problem with your principal profile.

    Solution: Confirm that your default principal profile is correct.

  • Problem: Double-check the case you used when entering the realm name.

    Solution: Typically, it should be uppercase. If you are using a DCE security server, the cell name (DCE equivalent of realm) must be lowercase.
