<DL>
<!-- ============================================================== -->
<!-- inAuthContext -->
<!-- ============================================================== -->
<DT>
<STRONG>inAuthContext</STRONG>&nbsp;&nbsp;(Input)
<DD>The authentication context to delegate.
The identity context OID indicates the type of authentication
context that is being delegated and returned.
This OID should match the OID in the identity context.
For the format of the structure, see the ictxIdContext structure in
the <A
href="ictxidcontext.htm">
ictxIdContext--Identity Context Parameter</A>.
<BR>
<BR>
<!-- ============================================================== -->
<!-- delegateInfo -->
<!-- ============================================================== -->
<DT>
<STRONG>delegateInfo</STRONG>&nbsp;&nbsp;(Input)
<DD>The information to be added to the authentication context.
This information is dependent on the type of authentication context
that is to be built.
For the format of the structure, see the ictxAuthContextInfo structure in
the <A
href="ictxauthcontextinfo.htm">
ictxAuthContextInfo--Authentication Context Information Parameter</A>.
<BR>
<BR>
<!-- ============================================================== -->
<!-- options -->
<!-- ============================================================== -->
<DT>
<STRONG>options</STRONG>&nbsp;&nbsp;(Input)
<DD>The options that can be specified for the identity context
reference.
This parameter may be NULL. If this parameter is NULL, the default
values will be used for the options. For the format of the structure,
see <A href="ictxoptions.htm">
ictxOptions--Identity Context Options Parameter</A>.
<BR>
<BR>
<!-- ============================================================== -->
<!-- authContext -->
<!-- ============================================================== -->
<DT>
<STRONG>authContext</STRONG>&nbsp;&nbsp;(Output)
<DD>Return pointer to an authentication context object.
When this context is no longer needed,
it must be freed using the Free Identity Context (ictxFreeIdContext) API.
For the format of the structure, see the ictxIdContext structure in
the <A
href="ictxidcontext.htm">
ictxIdContext--Identity Context Parameter</A>.
<BR>
<BR>
<!-- ============================================================== -->
<!-- errorInfo -->
<!-- ============================================================== -->
<DT>
<STRONG>errorInfo</STRONG>&nbsp;&nbsp;(Output)
<DD>The structure in which to return error code information. If the return
value is not 0, <EM>errorInfo</EM> is set with additional information. This
parameter may be NULL. For the format of the structure, see <A
href="ictxerror.htm">ictxError--Identity
Context Return Code Parameter</A>.
