KRB5_GET_CREDENTIALS(3)	    Library Functions Manual   KRB5_GET_CREDENTIALS(3)

NAME
       krb5_get_credentials,		      krb5_get_credentials_with_flags,
       krb5_get_kdc_cred, krb5_get_renewed_creds -- get	credentials  from  the
       KDC using krbtgt

LIBRARY
       Kerberos	5 Library (libkrb5, -lkrb5)

SYNOPSIS
       #include	<krb5.h>

       krb5_error_code
       krb5_get_credentials(krb5_context context,	   krb5_flags options,
	   krb5_ccache ccache, krb5_creds *in_creds, krb5_creds	**out_creds);

       krb5_error_code
       krb5_get_credentials_with_flags(krb5_context context,
	   krb5_flags options,	  krb5_kdc_flags flags,	   krb5_ccache ccache,
	   krb5_creds *in_creds, krb5_creds **out_creds);

       krb5_error_code
       krb5_get_kdc_cred(krb5_context context,		       krb5_ccache id,
	   krb5_kdc_flags flags,		    krb5_addresses *addresses,
	   Ticket *second_ticket,			 krb5_creds *in_creds,
	   krb5_creds **out_creds);

       krb5_error_code
       krb5_get_renewed_creds(krb5_context context,	    krb5_creds *creds,
	   krb5_const_principal	client,			   krb5_ccache ccache,
	   const char *in_tkt_service);

DESCRIPTION
       krb5_get_credentials_with_flags()   get	 credentials   specified    by
       in_creds->server	 and in_creds->client (the rest	of the in_creds	struc-
       ture is ignored)	by first looking in the	ccache and if  doesn't	exists
       or  is  expired,	 fetch the credential from the KDC using the krbtgt in
       ccache.	The credential is returned in out_creds	and  should  be	 freed
       using the function krb5_free_creds().

       Valid flags to pass into	options	argument are:

       KRB5_GC_CACHED	   Only	 check the ccache, don't got out on network to
			   fetch credential.
       KRB5_GC_USER_USER   Request a user to user ticket.  This	option doesn't
			   store the resulting user to user credential in  the
			   ccache.
       KRB5_GC_EXPIRED_OK  returns  the	 credential even if it is expired, de-
			   fault behavior is trying to refetch the  credential
			   from	the KDC.

       Flags  are  KDCOptions,	note the caller	must fill in the bit-field and
       not use the integer associated structure.

       krb5_get_credentials()	   works      the      same	  way	    as
       krb5_get_credentials_with_flags()  except that the flags	field is miss-
       ing.

       krb5_get_kdc_cred() does	the same  as  the  functions  above,  but  the
       caller  must fill in all	the information	andits closer to the wire pro-
       tocol.

       krb5_get_renewed_creds()	renews a credential  given  by	in_tkt_service
       (if  NULL  the  default krbtgt) using the credential cache ccache.  The
       result is stored	in creds and should be freed using krb5_free_creds.

EXAMPLES
       Here is a example function that get  a  credential  from	 a  credential
       cache id	or the KDC and returns it to the caller.

       #include	<krb5.h>

       int
       getcred(krb5_context context, krb5_ccache id, krb5_creds	**creds)
       {
	   krb5_error_code ret;
	   krb5_creds in;

	   ret = krb5_parse_name(context, "client@EXAMPLE.COM",
				 &in.client);
	   if (ret)
	       krb5_err(context, 1, ret, "krb5_parse_name");

	   ret = krb5_parse_name(context, "host/server.example.com@EXAMPLE.COM",
				 &in.server);
	   if (ret)
	       krb5_err(context, 1, ret, "krb5_parse_name");

	   ret = krb5_get_credentials(context, 0, id, &in, creds);
	   if (ret)
	       krb5_err(context, 1, ret, "krb5_get_credentials");

	   return 0;
       }
