krb5_get_in_tkt_with_password -> gss_init_sec_context()

[vir vir]

Hi,
 
I am trying to get a credential cache (krb5_ccache) using the functions krb5_get_in_tkt_with_password() or get the credential handle  (krb5_creds)krb5_get_init_creds_password() and then use this  credential in gss_init_sec_context().
I find out that there is a function call gss_krb5_acquire_cred_ccache() 
allows an application to acquire a GSS-API credential using a credentials cache.
but MIT doesn't support this function.
Do you know how I after I am getting the  credential  for the "password" function I can use it in gss_init_sec_context().
Thanks,
Alex
