It's been very hard to use since we made krb5_kdc_rep_decrypt_proc private (in krb5 1.7 the prototype was taken out of krb5.h altogether), and it's unlikely that anything would have used it directly in the first place.

| | | | | | | | | | | | get the cached local TGT before setting up the realm path. Prior to this change, calling krb5_get_credentials() with an empty ccache would result in KRB5_CC_NOTFOUND for a foreign server principal, but would result in KRB5_NO_TKT_IN_REALM (generated by krb5_walk_realm_tree) for a local server principal. With this change, KRB5_CC_NOTFOUND is returned in both cases. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23909 dc483132-0cff-0310-8789-dd5450dbe970

| | | | | | | | | | | | Merged from branches/iakerb: add new asynchronous krb5_tkt_creds APIs, which allow a caller to take responsibility for transporting requests to the KDC and getting responses back. Rewrite the existing krb5_get_credentials API in terms of the new functions. Get rid of krb5_get_cred_from_kdc and friends, since they are no longer used. ticket: 6700 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23900 dc483132-0cff-0310-8789-dd5450dbe970
* Validate and renew should work on non-TGT credsGreg Hudson2010-04-133-151/+197
| | | | | | | | | | | | | The validate and renew APIs were using get_cred_from_kdc, which always presents a TGT to get credentials. Instead, they should present the ticket they are trying to validate or renew. This is most easily done with krb5_get_cred_via_tkt(). Move the relevant code into a new file since it now has nothing in common with the other APIs implemented in get_creds.c. ticket: 6699 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23891 dc483132-0cff-0310-8789-dd5450dbe970

| | | | | | | | | | | | krb5_init_creds_step() is taken from Heimdal, which sets *flags to 1 for "continue" and 0 for "stop".
