sasl_server_step − Perform a step in the authentication negotiation

sasl_server_step() performs a step in the authentication negotiation. It returns SASL_OK if the whole negotiation is sucessful and SASL_CONTINUE if this step is ok but at least one more step is needed.
errstr is sometimes returned on error and gives a mechanism specific reason for failure. This information should not be given to the client.
conn is the SASL connection context clientin is the data given by the client (decoded if the protocol encodes requests sent over the wire) clientinlen is the length of clientin serverout and serveroutlen is allocated by the library and should be sent to the client.
sasl_server_step returns an integer which corresponds to one of the following codes. SASL_CONTINUE indicates sucess and that there are more steps needed in the authentication. SASL_OK indicates that the authentication is complete. All other return codes indicate errors and should either be handled or the authentication session should be quit.
