As per documentation (http://www.symantec.com/docs/DOC6232 )
--usp-server is provided. --recipient specifies the UUID of the recipient's MAK or MEK, or the recipient's user ID, portion of the user ID, or the key ID. PGP Command Line searches the server for the recipient key. An error results if PGP Command Line can match the identifier to multiple MAKs or MEKs on the PGP KMS server.
The --search-mak command searches a PGP KMS for a MAK.
The usage format is:
pgp --search-mak <search-string> --usp-server <KMSserver> -details | --xml | --brief
Where: • --search-mak is the command to search MAKs on the specified PGP KMS.
So your pgp command line should have --search-mak otherwise keys are searched locally.
pgp --usp-server <IP Address> --auth-username <username> --auth-passphrase "<passphrase>" --search-mak <search-string>
(page 254 - shows search strings options)
(page 61 of the documentation shows the encrypt command)
