krb5_auth_con_setuseruserkey -- Set keyblock field in auth_context to temporary key 

C Prototype 

krb5_error_code krb5_auth_con_setuseruserkey(
         krb5_context           context,
         krb5_auth_context      auth_context,
         krb5_keyblock          *keyblock );   

Arguments 

context (input/output)		The context structure.
auth_context (input/output)
		A per-connection context.
keyblock (input)		Server key for incoming request.

Description 

This routine overloads the keyblock field. It is only useful prior to a krb5_rd_req_decode call for user-to-user authentication where the server has the key and needs to use it to decrypt the incoming request. Once decrypted, this key is no longer necessary. It is then overwritten with the session key sent by the client.

Return Values 

This routine returns the following KRB5 status code:

0	Successful completion.
ENOMEM	Insufficient memory.
