All,
Could you please help with information i'm replacing the heimdal calls into
mit.
char * serverRealm = "CSQALAB.NET"
char * HTTPSVC = "HTTP"
char * server = "Parent-2K16.csqalab.net"
krb5_creds inCred, outCred;
memset(&inCred, 0, sizeof(inCred));
memset(&outCred, 0, sizeof(outCred));
#if heimdal
m_error = krb5_make_principal(m_context, &inCred.server,
serverRealm, HTTPSVC, server, NULL);
if (m_error == 0) {
m_error = krb5_cc_retrieve_cred(m_context, m_cache, flags,
&inCred, &outCred);
}
#endif
#if MIT
m_error =krb5_build_principal_ext(m_context,&inCred.server,
strlen(serverRealm), serverRealm,
strlen(HTTPSVC),HTTPSVC,
strlen(server),server,
0);
if (m_error == 0) {
m_error = krb5_cc_retrieve_cred(m_context, m_cache, flags,
&inCred, &outCred);
}
i'm getting crash:
(gdb) bt

should i use code = krb5int_construct_matching_creds(context, options,
in_creds, &mcreds, &fields); before calling retrive from cache.
