RE: [cas-user] Configure SAML2 IdP functionality to provide SSO for G Suite
Yep. The certificate was the issue. I do have it working now but I have two
questions regarding warnings I am seeing.
I get the following warning:
WARN [org.opensaml.saml.common.binding.SAMLBindingSupport] - https://www.google.com/a/example.com/ServiceLogin?service=mail=true=false=https%3A%2F%2Fmail.google.com%2Fmail%2F=1=default=2=1=1>
Is this normal and a result of the way G Suite does SAML? Or is there
something I can configure to make CAS happy and not feel the need to warn me.
Also, I get this warning upon signing out of G Suite:
WARN
[org.apereo.cas.support.saml.web.idp.profile.slo.SamlIdPSingleLogoutServiceLogoutUrlBuilder]
-
I read somewhere online that Google does not provide Single Log Out (SLO). Is
there a way to disable SLO for a service so I don't get this warning? I want
to keep SLO enabled in general.
Thanks!
Instructions for Others
In case someone else is trying to figure this out. Here are what I think
constitutes all the steps that I took to get this working. You should replace
all instances of example.com and cas-server-url with what is appropriate the
system being configured.
1. Add the following dependency in the WAR overlay build.gradle file.
implementation
"org.apereo.cas:cas-server-support-saml-idp:${project.'cas.version'}"
2. Add the following line to cas.properties.
cas.authn.saml-idp.entity-id=https://cas-server-url/cas/idp
3. Create a service definition file in /etc/cas/services.
{
"@class" : "org.apereo.cas.support.saml.services.SamlRegisteredService",
"serviceId" : "google.com/a/example.com",
"name" : "G Suite",
"id" : 1002,
"evaluationOrder" : 1,
"attributeReleasePolicy" : {
"@class" : "org.apereo.cas.services.ReturnAllowedAttributeReleasePolicy",
"allowedAttributes" : [ "java.util.ArrayList", [ "mail" ] ]
},
"usernameAttributeProvider" : {
"@class" :
"org.apereo.cas.services.PrincipalAttributeRegisteredServiceUsernameProvider",
"usernameAttribute" : "mail"
}
"metadataLocation" : "/etc/cas/saml/sp-metadata.xml",
"metadataSignatureLocation" : "/etc/cas/saml/idp-signing.crt"
}
4. Create a directory /etc/cas/saml.
5. Generate certificates.
openssl genrsa -out /etc/cas/saml/idp-encryption.key 2048
openssl req -new -x509 -key /etc/cas/small/idp-encryption.key -out
/etc/cas/saml/idp-encryption.crt -days 3650
openssl genrsa -out /etc/cas/saml/idp-signing.key 2048
openssl req -new -x509 -key /etc/cas/saml/idp-signing.key -out
/etc/cas/saml/idp-signing.crt -days 3650
6. Create idp-metadata.xml in /etc/cas/saml with the following contents.
Note: REPLACE_WITH_..._CERTIFICATE should be replaced with everything between
the “-BEGIN CERTIFICATE-“ and “-END CERTIFICATE-“ in the
corresponding .crt file.
http://www.w3.org/2000/09/xmldsig#;
xmlns:shibmd="urn:mace:shibboleth:metadata:1.0"
xmlns:xml="http://www.w3.org/XML/1998/namespace;
xmlns:mdui="urn:oasis:names:tc:SAML:metadata:ui"
entityID="https://cas-server-url/cas/idp;>
REPLACE_WITH_SIGNING_CERTIFICATE
REPLACE_WITH_ENCRYPTION_CERTIFICATE
https://cas-server-url/cas/idp/profile/SAML2/POST/SLO"/>
https://cas-server-url/cas/idp/profile/SAML2/Redirect/SLO; />
urn:mace:shibboleth:1.0:nameIdentifier
urn:oasis:names:tc:SAML:2.0:nameid-format:transient
https://cas-server-url/cas/idp/profile/SAML2/POST/SSO"/>
https://cas-server-url/cas/idp/profile/SAML2/POST-SimpleSign/SSO"/>
https://cas-server-url/cas/idp/profile/SAML2/Redirect/SSO"/>
https://cas-server-url/cas/idp/profile/SAML2/SOAP/ECP"/>
7. Create sp-metadata.xml in /etc/cas/saml with the following contents.
http://www.w3.org/2000/09/xmldsig#;>
REPLACE_WITH_SIGNING_CERTIFICATE
http://www.w3.org/2000/09/xmldsig#;>
REPLACE_WITH_ENCRYPTION_CERTIFICATE
urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified
https://www.google.com/a/example.com/acs; index="1"/>
8. In the G Suite Admin Console "Set up single sign-on (SSO) with a third
party IdP" section:
a. Checked the box for "Set up SSO with third-party identity provider"
b. Entered "https://cas-server-url/cas/idp/profile/SAML2/Redirect/SSO; for
"Sign-in page URL"
c. Entered "https://cas-server-url/cas/logout; for "Sign-out page URL"
d. Checked "Use a domain specific identifier"
e. Uploaded the idp-signing.crt certificate.
Hopefully I didn’t leave anything out and this will help out the next person.

Ran gradlew clean build then debug mode gradle run. After I login, i get a ticket issued. I expected to hit a break point in SomethingWebflowConfigurer class but I don't.

Re: [cas-user] Configure SAML2 IdP functionality to provide SSO for G Suite
The cert you were using under the old integration likely doesn't match your
SAML cert. You would need to upload your new SAML cert to Google. And yeah, you
want to remove the old bits of the old method, in particular the jars
associated with it as it fires before the generic SAML can.

Responding a little to my own question. I don’t have it fully figured out yet
but I did find a significant issue. I had left my service file for the old
Google Apps SAML integration method in my services directory and I think this
was intercepting things. I’m not getting the same error as before but when I
authenticated I got back a page from Google indicating that no such account
existed. I’m going to try again and see what I can find perhaps see if I can
turn of the debugging.

Subject: [cas-user] Configure SAML2 IdP functionality to provide SSO for G Suite
I have been working toward updating from CAS 6.0.x to CAS 6.2.x. Most
everything has gone smoothly but I am having trouble with setting up CAS to be
my G Suite third-party Idp. Previously I had been using the Google Apps
Integration (org.apereo.cas:cas-server-support-saml-googleapps) but the page
for that
(https://apereo.github.io/cas/6.2.x/integration/Google-Apps-Integration.html)
now indicates that it is deprecated and that I should consider using the SAML2
identity provider functionality to handle this. I have tried to piece together
information in the documentation and in other folk's questions in the cas-user
forum but I seem to be missing something. This is likely due to my lack of
familiarity with SAML.
I would appreciate any help or direction on getting this working.
This is what I have done so far.
Note: I have replaced the references to my G Suite primary domain with
example.com for this posting.
I created a services file (etc/cas/services/GSuite-1003.json) with the
following content:
{
"@class" : "org.apereo.cas.support.saml.services.SamlRegisteredService",
"serviceId" : "google.com/a/example.com",
"name" : "SAMLService",
"id" : 1003,
"evaluationOrder" : 1,
"attributeReleasePolicy" : {
"@class" : "org.apereo.cas.services.ReturnAllowedAttributeReleasePolicy",
"allowedAttributes" : [ "java.util.ArrayList", [ "mail" ] ]
},
"usernameAttributeProvider" : {
"@class" :
"org.apereo.cas.services.PrincipalAttributeRegisteredServiceUsernameProvider",
"usernameAttribute" : "mail"
}
"metadataLocation" : "/etc/cas/saml/sp-metadata.xml"
}
I also created an sp-metadata.xml file using
https://www.samltool.com/sp_metadata.php with the following contents:
urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified
https://www.google.com/a/example.com/acs;
index="1" />
I also included the following dependency in the CAS overlay:
implementation
"org.apereo.cas:cas-server-support-saml-idp:${project.'cas.version'}"
In G Suite Admin Console "Set up single sign-on (SSO) with a third party IdP" I:
1. Checked the box for "Set up SSO with third-party identity provider"
2. Entered
"https://signin.my-cas-server.com/cas/idp/profile/SAML2/Redirect/SSO; for
"Sign-in page URL"
3. Entered "https://signin.my-cas-server.com/cas/logout; for "Sign-out page URL"
4. Checked "Use a domain specific identifier"
5. Uploaded the previous x.509 certificate that I had used when using the
previous method.
At the moment, when I attempt to load a Google service I am redirected back to
my CAS server but I receive the following error message:
Error: No metadata resolvers could be configured for service SAMLService with
metadata location /etc/cas/saml/sp-metadata.xml
I am guessing that this is something to do with my sp-metadata.xml file missing
something but I am at a loss as to what I need to do.
Any help appreciated. Thanks!
Doug

Marc, I'd suggest taking a look at JDBC Audits - https://apereo.github.io/cas/6.2.x/installation/Audits.html#database-audits I won't do exactly what you want, but you'll be able to get a last login date from the table it creates.

[cas-user] Update a date database field on successful login
Hello, I'm using jdbc/mysql to authenticate my users. I have a simple need : I want to add a last_login_date field, updated at each successful login I want to be able to know if some accounts have not been used from a very long time. I red carefully the doc and reviewed the list of properties, but I see nothing about that. Do I need to write some custom code ? Do you know what code or class I should extend ? note: just updated my overlay to 6.2 successfully.
