27 | * Changes: | |
28 | * July 6, 1999 - Rewrote most of the code here. When a client connects | |
29 | * to the server and passes initial socket validation checks, it | |
30 | * is owned by this module (auth) which returns it to the rest of the | |
31 | * server when dns and auth queries are finished. Until the client is | |
32 | * released, the server does not know it exists and does not process | |
33 | * any messages from it. | |
