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.
