source: trunk/athena/bin/lert/lertload.c @ 17860

Revision 17860, 2.1 KB checked in by zacheiss, 22 years ago (diff)
Implement v2 of the protocol, which uses krb5 for authentication. Leave v1 protocol support in the server for backwards compatability for now. Remove unused variables and modernize the declaration of main(), too.
