<p>The <strong>gss_add_cred()</strong> function adds a credential element to an
|
|
existing GSS credential. The credential must not already contain an element for
|
|
the mechanism. A GSS credential must contain an element for each mechanism that
|
|
will be used for contexts that are initiated or accepted using the
|
|
credential.</p>

The i5/OS implementation of GSS does not support separate initiate and accept

initiate and accept times. Specify zero to request the default lifetime of 2

credential and contains all of the credential elements of the input credential

<h3>Usage Notes</h3>
|
|
|
|
<ol>
|
|
<li>The <strong>gss_add_cred()</strong> routine performs the same functionas
|
