If you are one of the many IdPs that already supports CILogon, it is very easy to convert your CILogon configuration to a more general R&S configuration since the attribute requirements for CILogon are precisely those attributes required for support of R&S.
Software Requirements
The software requirements for the configuration documented here require Shibboleth IdP v2.3.4 or later.
Your current CILogon configuration probably looks something like this:
<AttributeFilterPolicy id="releaseToCILogon">
<PolicyRequirementRule xsi:type="basic:AttributeRequesterString"
value="https://cilogon.org/shibboleth"/>
<AttributeRule attributeID="eduPersonPrincipalName">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
<AttributeRule attributeID="email">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
<AttributeRule attributeID="displayName">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
<AttributeRule attributeID="givenName">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
<AttributeRule attributeID="surName">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
</AttributeFilterPolicy>
Now simply replace the CILogon entityID with the R&S entity attribute:
<AttributeFilterPolicy id="releaseToRandS">
<PolicyRequirementRule xsi:type="saml:AttributeRequesterEntityAttributeExactMatch"
attributeName="http://macedir.org/entity-category"
attributeValue="http://id.incommon.org/category/research-and-scholarship"/>
<AttributeRule attributeID="eduPersonPrincipalName">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
<AttributeRule attributeID="email">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
<AttributeRule attributeID="displayName">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
<AttributeRule attributeID="givenName">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
<AttributeRule attributeID="surName">
<PermitValueRule xsi:type="basic:ANY"/>
</AttributeRule>
</AttributeFilterPolicy>
That's it, you're done. Congratulations, you've just given your users access to all R&S SPs.
