-.Sh DESCRIPTION
-Generic Security Service API (GSS-API) version 2, and its C binding,
-is described in
-.Li RFC2743
-and
-.Li RFC2744 .
-Version 1 (deprecated) of the C binding is described in
-.Li RFC1509 .
-.Pp
-Heimdals GSS-API implementation supports the following mechanisms
-.Bl -bullet
-.It
-.Li GSS_KRB5_MECHANISM
-.It
-.Li GSS_SPNEGO_MECHANISM
-.El
-.Pp
-GSS-API have generic name types that all mechanism are supposed to
-implement (if possible):
-.Bl -bullet
-.It
-.Li GSS_C_NT_USER_NAME
-.It
-.Li GSS_C_NT_MACHINE_UID_NAME
-.It
-.Li GSS_C_NT_STRING_UID_NAME
-.It
-.Li GSS_C_NT_HOSTBASED_SERVICE
-.It
-.Li GSS_C_NT_ANONYMOUS
-.It
-.Li GSS_C_NT_EXPORT_NAME
-.El
-.Pp
-GSS-API implementations that supports Kerberos 5 have some additional
-name types:
-.Bl -bullet
-.It
-.Li GSS_KRB5_NT_PRINCIPAL_NAME
-.It
-.Li GSS_KRB5_NT_USER_NAME
-.It
-.Li GSS_KRB5_NT_MACHINE_UID_NAME
-.It
-.Li GSS_KRB5_NT_STRING_UID_NAME
-.El
-.Pp
-In GSS-API, names have two forms, internal names and contiguous string
-names.
-.Bl -bullet
-.It
-.Li Internal name and mechanism name
-.Pp
-Internal names are implementation specific representation of
-a GSS-API name.
-.Li Mechanism names
-special form of internal names corresponds to one and only one mechanism.
-.Pp
-In GSS-API an internal name is stored in a
-.Dv gss_name_t .
-.It
-.Li Contiguous string name and exported name
-.Pp
-Contiguous string names are gssapi names stored in a
-.Dv OCTET STRING
-that together with a name type identifier (OID) uniquely specifies a
-gss-name.
-A special form of the contiguous string name is the exported name that
-have a OID embedded in the string to make it unique.
-Exported name have the nametype
-.Dv GSS_C_NT_EXPORT_NAME .
-.Pp
-In GSS-API an contiguous string name is stored in a
-.Dv gss_buffer_t .
-.Pp
-Exported names also have the property that they are specified by the
-mechanism itself and compatible between diffrent GSS-API
-implementations.
-.El
-.Sh ACCESS CONTROL
-There are two ways of comparing GSS-API names, either comparing two
-internal names with each other or two contiguous string names with
-either other.
-.Pp
-To compare two internal names with each other, import (if needed) the
-names with
-.Fn gss_import_name
-into the GSS-API implementation and the compare the imported name with
-.Fn gss_compare_name .
-.Pp
-Importing names can be slow, so when its possible to store exported
-names in the access control list, comparing contiguous string name
-might be better.
-.Pp
-when comparing contiguous string name, first export them into a
-.Dv GSS_C_NT_EXPORT_NAME
-name with
-.Fn gss_export_name
-and then compare with
-.Xr memcmp 3 .
-.Pp
-Note that there are might be a difference between the two methods of
-comparing names.
-The first (using
-.Fn gss_compare_name )
-will compare to (unauthenticated) names are the same.
-The second will compare if a mechanism will authenticate them as the
-same principal.
-.Pp
-For example, if
-.Fn gss_import_name
-name was used with
-.Dv GSS_C_NO_OID
-the default syntax is used for all mechanism the GSS-API
-implementation supports.
-When compare the imported name of
-.Dv GSS_C_NO_OID
-it may match serveral mechanism names (MN).
-.Pp
-The resulting name from
-.Fn gss_display_name
-must not be used for acccess control.
-.Sh FUNCTIONS
-.Fn gss_display_name
-takes the gss name in
-.Fa input_name
-and puts a printable form in
-.Fa output_name_buffer .
-.Fa output_name_buffer
-should be freed when done using
-.Fn gss_release_buffer .
-.Fa output_name_type
-can either be
-.Dv NULL
-or a pointer to a
-.Li gss_OID
-and will in the latter case contain the OID type of the name.
-The name must only be used for printing.
-If access control is needed, see section
-.Sx ACCESS CONTROL .
-.Pp
-.Fn gss_inquire_context
-returns information about the context.
-Information is available even after the context have expired.
-.Fa lifetime_rec
-argument is set to
-.Dv GSS_C_INDEFINITE
-(dont expire) or the number of seconds that the context is still valid.
-A value of 0 means that the context is expired.
-.Fa mech_type
-argument should be considered readonly and must not be released.
-.Fa src_name
-and
-.Fn dest_name
-are both mechanims names and must be released with
-.Fn gss_release_name
-when no longer used.
-.Pp
-.Nm gss_context_time
-will return the amount of time (in seconds) of the context is still
-valid.
-If its expired
-.Fa time_rec
-will be set to 0 and
-.Dv GSS_S_CONTEXT_EXPIRED
-returned.
-.Pp
-.Fn gss_sign ,
-.Fn gss_verify ,
-.Fn gss_seal ,
-and
-.Fn gss_unseal
-are part of the GSS-API V1 interface and are obsolete.
-The functions should not be used for new applications.
-They are provided so that version 1 applications can link against the
-library.
-.Sh EXTENSIONS
-.Fn gss_krb5_ccache_name
-sets the internal kerberos 5 credential cache name to
-.Fa name .
-The old name is returned in
-.Fa old_name ,
-and must not be freed.
-The data allocated for
-.Fa old_name
-is free upon next call to
-.Fn gss_krb5_ccache_name .
-This function is not threadsafe if
-.Fa old_name
-argument is used.
-.Pp
-.Fn gss_krb5_copy_ccache
-will extract the krb5 credentials that are transferred from the
-initiator to the acceptor when using token delegation in the Kerberos
-mechanism.
-The acceptor receives the delegated token in the last argument to
-.Fn gss_accept_sec_context .
-.Pp
-.Fn gss_krb5_import_cred
-will import the krb5 credentials (both keytab and/or credential cache)
-into gss credential so it can be used withing GSS-API.
-The
-.Fa ccache
-is copied by reference and thus shared, so if the credential is destroyed
-with
-.Fa krb5_cc_destroy ,
-all users of thep
-.Fa gss_cred_id_t
-returned by
-.Fn gss_krb5_import_ccache
-will fail.
-.Pp
-.Fn gsskrb5_register_acceptor_identity
-sets the Kerberos 5 filebased keytab that the acceptor will use.  The
-.Fa identifier
-is the file name.
-.Pp
-.Fn gsskrb5_extract_authz_data_from_sec_context
-extracts the Kerberos authorizationdata that may be stored within the
-context.
-Tha caller must free the returned buffer
-.Fa ad_data
-with
-.Fn gss_release_buffer
-upon success.
-.Pp
-.Fn gss_krb5_get_tkt_flags
-return the ticket flags for the kerberos ticket receive when
-authenticating the initiator.
-Only valid on the acceptor context.
-.Pp
-.Fn gss_krb5_compat_des3_mic
-turns on or off the compatibility with older version of Heimdal using
-des3 get and verify mic, this is way to programmatically set the
-[gssapi]broken_des3_mic and [gssapi]correct_des3_mic flags (see
-COMPATIBILITY section in
-.Xr gssapi 3 ) .
-If the CPP symbol
-.Dv GSS_C_KRB5_COMPAT_DES3_MIC
-is present,
-.Fn gss_krb5_compat_des3_mic
-exists.
-.Fn gss_krb5_compat_des3_mic
-will be removed in a later version of the GSS-API library.
