One of the colleges here uses Shibboleth for TEAMS authentication. Having no issues with this, they decided to install<o:p></o:p></span></p>

<p class="MsoNormal">this activity when I received a phone call from some Microsoft engineers who wanted to know if the session timeout
<o:p></o:p></p>
<p class="MsoNormal">could be extended indefinitely (they claimed that a “token” from Shibboleth was timing out) or if the authentication
<o:p></o:p></p>
<p class="MsoNormal">could be renewed without the user having to login.<o:p></o:p></p>
