DESCRIPTION

       All the functions in this manual page are  deprecated  in  the  MIT  implementation,  and  will  soon  be
       deprecated in Heimdal too, don't use them.

       Getting  initial  credential  ticket  for  a  principal.   krb5_get_in_cred  is  the  function  all other
       krb5_get_in function uses to fetch tickets.  The other krb5_get_in  function  are  more  specialized  and
       therefor somewhat easier to use.

       If your need is only to verify a user and password, consider using krb5_verify_user(3) instead, it have a
       much simpler interface.

       krb5_get_in_tkt  and  krb5_get_in_cred  fetches  initial credential, queries after key using the key_proc
       argument.  The differences between the two function is that krb5_get_in_tkt stores the  credential  in  a
       krb5_creds while krb5_get_in_cred stores the credential in a krb5_ccache.

       krb5_get_in_tkt_with_password,  krb5_get_in_tkt_with_keytab,  and krb5_get_in_tkt_with_skey does the same
       work as krb5_get_in_cred but are more specialized.

       krb5_get_in_tkt_with_password uses the clients password to authenticate.  If  the  password  argument  is
       NULL the user user queried with the default password query function.

       krb5_get_in_tkt_with_keytab  searches  the given keytab for a service entry for the client principal.  If
       the keytab is NULL the default keytab is used.

       krb5_get_in_tkt_with_skey uses a key to get the initial credential.

       There are some common arguments to the krb5_get_in functions, these are:

       options are the KDC_OPT flags.

       etypes is a NULL terminated array of encryption types that the client approves.

       addrs a list of the addresses that the initial ticket.  If it is NULL the list will be generated  by  the
       library.

       pre_auth_types  a  NULL  terminated  array  of  pre-authentication  types.  If pre_auth_types is NULL the
       function will try without pre-authentication and return those pre-authentication that the KDC returned.

       ret_as_reply will (if not NULL) be filled in with the response  of  the  KDC  and  should  be  free  with
       krb5_free_kdc_rep().

       key_proc  is  a pointer to a function that should return a key salted appropriately.  Using NULL will use
       the default password query function.

       decrypt_proc Using NULL will use the default decryption function.

       decryptarg will be passed to the decryption function decrypt_proc.

       creds creds should be filled in with the template for a credential that should be requested.  The  client
       and  server  elements  of  the creds structure must be filled in.  Upon return of the function it will be
       contain  the  content  of  the  requested  credential  (krb5_get_in_cred),  or  it  will  be  freed  with
       krb5_free_creds(3) (all the other krb5_get_in functions).

       ccache  will  store  the  credential  in  the  credential cache ccache.  The credential cache will not be
       initialized, thats up the the caller.

       krb5_password_key_proc is a library function that is suitable using  as  the  krb5_key_proc  argument  to
       krb5_get_in_cred  or  krb5_get_in_tkt.   keyseed  should be a pointer to a NUL terminated string or NULL.
       krb5_password_key_proc will query the user for the pass on the console if the password isn't given as the
       argument keyseed.

       krb5_free_kdc_rep() frees the content of rep.
