A new field was added to the keyfile in 2.4.5 that checks for remote gem access to the stone. Older keyfiles can still be used in 2.4.5 and later versions (prior to 3.0), but since this field appears as FALSE on these older keyfiles, attempts to run a remote gem will trigger the following error during login:
GemStone: Error Fatal
Remote logins to this repository are disabled in the keyfile.
Contact GemTalk Technical Support for a new keyfile.
