principal.
New tickets will be obtained as a side-effect and stored in
ccache
(if
NULL,
the default ccache is used).
krb5_verify_user()
will call
krb5_cc_initialize()
on the given
ccache,
so
ccache
must only initialized with
krb5_cc_resolve()
or
krb5_cc_gen_new().
If the password is not supplied in
password
(and is given as
NULL)
the user will be prompted for it.
If
secure
the ticket will be verified against the locally stored service key
service
(by default
`host'
if given as
NULL
).
The
krb5_verify_user_lrealm()
function does the same, except that it ignores the realm in
principal
and tries all the local realms (see
krb5.conf(5)).
After a successful return, the principal is set to the authenticated
realm. If the call fails, the principal will not be meaningful, and
should only be freed with
krb5_free_principal(3).
krb5_verify_opt_alloc()
and
krb5_verify_opt_free()
allocates and frees a
krb5_verify_opt.
You should use the the alloc and free function instead of allocation
the structure yourself, this is because in a future release the
structure wont be exported.
krb5_verify_opt_init()
resets all opt to default values.
None of the krb5_verify_opt_set function makes a copy of the data
structure that they are called with. It's up the caller to free them
after the
krb5_verify_user_opt()
is called.
krb5_verify_opt_set_ccache()
sets the
ccache
that user of
opt
will use. If not set, the default credential cache will be used.
krb5_verify_opt_set_keytab()
sets the
keytab
that user of
opt
will use. If not set, the default keytab will be used.
krb5_verify_opt_set_secure()
if
secure
if true, the password verification will require that the ticket will
be verified against the locally stored service key. If not set,
default value is true.
krb5_verify_opt_set_service()
sets the
service
principal that user of
opt
will use. If not set, the
`host'
service will be used.
krb5_verify_opt_set_flags()
sets
flags
that user of
opt
will use.
If the flag
KRB5_VERIFY_LREALMS
is used, the
principal
will be modified like
krb5_verify_user_lrealm()
modifies it.
krb5_verify_user_opt()
function verifies the
password
supplied by a user.
The principal whose password will be verified is specified in
principal.
Options the to the verification process is pass in in
opt.
