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.
