- Get all functions prototyped or at least defined before use.
- Make code compile (Mostly) clean with -Wall set
- Start to reduce the degree to which DES aka libdes is built in.
- get all functions to the same uniform standard of definition:
int
foo(a, b)
int a;
int *b;
{
:
}
- fix numerous bugs exposed by above processes.
Note - this replaces the previous work which used an unpopular function
definition style.

* Get a ticket for the password-changing server ("changepw.KRB_MASTER").
|
|
*
|
|
* Given the name, instance, realm, and current password of the
|
|
* principal for which the user wants a password-changing-ticket,
|
|
* return either:
|
|
*
|
|
* GT_PW_BADPW if current password was wrong,
|
|
* GT_PW_NULL if principal had a NULL password,
|
|
* or the result of the krb_get_pw_in_tkt() call.
|
|
*
|
|
* First, try to get a ticket for "user.instance@realm" to use the
|
|
* "changepw.KRB_MASTER" server (KRB_MASTER is defined in "krb.h").
|
|
* The requested lifetime for the ticket is "1", and the current
|
|
* password is the "cpw" argument given.
|
|
*
|
|
* If the password was bad, give up.
|
|
*
|
|
* If the principal had a NULL password in the Kerberos database
|
|
* (indicating that the principal is known to Kerberos, but hasn't
|
|
* got a password yet), try instead to get a ticket for the principal
|
|
* "default.changepw@realm" to use the "changepw.KRB_MASTER" server.
|
|
* Use the password "changepwkrb" instead of "cpw". Return GT_PW_NULL
|
|
* if all goes well, otherwise the error.
|
|
*
|
|
* If this routine succeeds, a ticket and session key for either the
|
|
* principal "user.instance@realm" or "default.changepw@realm" to use
|
|
* the password-changing server will be in the user's ticket file.
