\bc serves requests for tickets. When it starts, it first checks the
14 flags passed, any options that are not specified with a command line flag
15 is taken from a config file, or from a default compiled-in value.

25 Turn off the requirement for pre-autentication in the initial AS-
26 REQ for all principals. The use of pre-authentication makes it
27 more difficult to do offline password attacks. You might want to
28 turn it off if you have clients that doesn't do pre-authentica-
29 tion. Since the version 4 protocol doesn't support any pre-au-
30 thentication, so serving version 4 clients is just about the same
31 as not requiring pre-athentication. The default is to require
32 pre-authentication. Adding the require-preauth per principal is a
33 more flexible way of handling this.

47 What realm this server should act as when dealing with version 4
48 requests. The database can contain any number of realms, but
49 since the version 4 protocol doesn't contain a realm for the

98 How long before password/principal expiration the KDC should
99 start sending out warning messages.
101 An example of a config file:
109 If the machine running the KDC has new addresses added to it, the KDC
110 will have to be restarted to listen to them. The reason it doesn't just
111 listen to wildcarded (like INADDR_ANY) addresses, is that the replies has
112 to come from the same address they were sent to, and most OS:es doesn't
113 pass this information to the application. If your normal mode of opera-
114 tion require that you add and remove addresses, the best option is proba-
115 bly to listen to a wildcarded TCP socket, and make sure your clients use
116 TCP to connect. For instance, this will listen to IPv4 TCP port 88 only:
118 kdc --addresses=0.0.0.0 --ports="88/tcp"
120 There should be a way to specify protocol, port, and address triplets,
121 not just addresses and protocol, port tuples.
