pcreddata will be decrypted using the receiving subkey if it is present in auth_context , or the session key if the receiving subkey is not present or fails to decrypt the message.

Use krb5_free_tgt_creds() to free pppcreds when it is no longer needed.


The outdata argument is required if KRB5_AUTH_CONTEXT_RET_TIME or KRB5_AUTH_CONTEXT_RET_SEQUENCE flag is set in the auth_context .`
