krb5_error_code krb5_get_renewed_creds(krb5_context context, krb5_creds * creds, krb5_principal client, krb5_ccache ccache, const char * in_tkt_service)
param:

[in] in_tkt_service - Server principal string (or NULL)

retval:
  • 0 Success
return:
  • Kerberos error codes

This function gets a renewed credential using an existing one from ccache . If in_tkt_service is specified, it is parsed (with the realm part ignored) and used as the server principal of the credential; otherwise, the ticket-granting service is used.

If successful, the renewed credential is placed in creds .
