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.
