SP 3.0.1 - IIS - Request Mapper failing on long Path Regex

[Igor Miltchman]

Hi,

As of the new SP release, the PathRegex appears to fail to establish an SP session within IIS, on RegEx string over 20 characters in length.

In the example below, if the regex is 'ABCD' or 'ABCD/SampleABC10000',  the path ABCD/SampleABC10000/Testing/Etc redirects to the IdP, but the regex of 'ABCD/SampleABC10000/Test' or 'ABCD/SampleABC10000/Testing/Etc' doesn't.

  <RequestMapper type="Native">
        <RequestMap>
            <Host scheme="http" name="servername.us-east-1.elb.amazonaws.com" port="80">
                <Path name="p">
                    <Path name="fa.aspx" forceAuthn="true" authType="shibboleth" requireSession="true"/>
                    <Path name="sso.aspx" forceAuthn="false" authType="shibboleth" requireSession="true"/>
                </Path>
                <PathRegex regex="ABCD/SampleABC10000/Testing/Etc" caseSensitive="false" forceAuthn="false" authType="shibboleth" requireSession="true"/>
            </Host>
        </RequestMap>
    </RequestMapper>

Everything worked on the initial upgrade, before the IIS configuration was updated.

Thank you,
Igor
