.Sh DESCRIPTION
|
|
||||||
The
|
|
||||||
.Li krb5_ccache
|
|
||||||
structure holds a Kerberos credential cache.
|
|
||||||
.Pp
|
|
||||||
The
|
|
||||||
.Li krb5_cc_cursor
|
|
||||||
structure holds current position in a credential cache when
|
|
||||||
iterating over the cache.
|
|
||||||
.Pp
|
|
||||||
The
|
|
||||||
.Li krb5_cc_ops
|
|
||||||
structure holds a set of operations that can me preformed on a
|
|
||||||
credential cache.
|
|
||||||
.Pp
|
|
||||||
There is no component inside
|
|
||||||
.Li krb5_ccache ,
|
|
||||||
.Li krb5_cc_cursor
|
|
||||||
nor
|
|
||||||
.Li krb5_fcc_ops
|
|
||||||
that is directly referable.
|
|
||||||
.Pp
|
|
||||||
The
|
|
||||||
.Li krb5_creds
|
|
||||||
holds a Kerberos credential, see manpage for
|
|
||||||
.Xr krb5_creds 3 .
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_cc_default_name
|
|
||||||
and
|
|
||||||
.Fn krb5_cc_set_default_name
|
|
||||||
gets and sets the default name for the
|
|
||||||
.Fa context .
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_cc_default
|
|
||||||
opens the default credential cache in
|
|
||||||
.Fa id .
|
|
||||||
Return 0 or an error code.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_cc_gen_new
|
|
||||||
generates a new credential cache of type
|
|
||||||
.Fa ops
|
|
||||||
in
|
|
||||||
.Fa id .
|
|
||||||
Return 0 or an error code.
|
|
||||||
The Heimdal version of this function also runs
|
|
||||||
.Fn krb5_cc_initialize
|
|
||||||
on the credential cache, but since the MIT version doesn't, portable
|
|
||||||
code must call krb5_cc_initialize.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_cc_new_unique
|
|
||||||
generates a new unique credential cache of
|
|
||||||
.Fa type
|
|
||||||
in
|
|
||||||
.Fa id .
|
|
||||||
If type is
|
|
||||||
.Dv NULL ,
|
|
||||||
the library chooses the default credential cache type.
|
|
||||||
The supplied
|
|
||||||
.Fa hint
|
|
||||||
(that can be
|
|
||||||
.Dv NULL )
|
|
||||||
is a string that the credential cache type can use to base the name of
|
|
||||||
the credential on, this is to make it easier for the user to
|
|
||||||
differentiate the credentials.
|
|
||||||
The returned credential cache
|
|
||||||
.Fa id
|
|
||||||
should be freed using
|
|
||||||
.Fn krb5_cc_close
|
|
||||||
or
|

.Fn krb5_cc_destroy .
|
|
||||||
Returns 0 or an error code.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_cc_resolve
|
|
||||||
finds and allocates a credential cache in
|
|
||||||
.Fa id
|
|
||||||
from the specification in
|
|
||||||
.Fa residual .
|
|
||||||
If the credential cache name doesn't contain any colon (:), interpret it as a
|
|
||||||
file name.
|
|
||||||
Return 0 or an error code.
|
|
||||||
.Pp
|
|
||||||
.Fn krb5_cc_initialize
|

.Pp
|
|
||||||
.Fn krb5_cc_close
|
|
||||||
stops using the credential cache
|
|
||||||
.Fa id
|
|
||||||
and frees the related resources.
|
|
||||||
Return 0 or an error code.
|
|
||||||
.Fn krb5_cc_destroy
|
|
||||||
removes the credential cache
|
|
||||||
and closes (by calling
|
|
||||||
.Fn krb5_cc_close )
|
