[GeoNetwork-devel] Shibboleth redirection problem with service "shib.user.login" on GeoNetwork 2.10.4

Hi,
I’m having problems with Shibboleth on GeoNetwork 2.10.4 (war).
I need to setup SSO but when I call the shib.user.login the browser send me the error “This page is not redirecting properly”.
I’ve followed this guide on github https://github.com/geosolutions-it/core-geonetwork/wiki/Shibboleth-setup-on-2.10.x and all is configured properly.
What can I do? I have the source code from github and I think is a Spring-security-web related problem but I don’t know how to resolve it.

Thanks,
Gioele Minardi

This is the error in catalina.out with GeoNetwork in DEBUG mode for logging:

Hi Gioele,

never seen this error before; anyway you may try reordering the filter list at
   https://github.com/geonetwork/core-geonetwork/blob/2.10.x/web/src/main/webapp/WEB-INF/config-security-core.xml#L60

Thanks Emanuele but It doesn’t work. I think that the error “This page is not redirecting properly” is somehow related to a redirection loop that is infinite, because in the tomcat’s log I have found that when I call the shib.user.login service, it throws an exception and after re-call the entry point, that is shib.user.login again. It calls himself for about 21 times and then the browser stops the request and visualizes the error. This error is launched only when I call the shib.user.login service after decommenting the line, in config-security.xml, with the import of the config-security-shibboleth.xml (I have rearranged the filters list here, also).

Could it be that the shibboleth authentication failed? So it tries
with the rest of the authentication chain. Do you have any other app
configured where you can test the login?

Regards,
María.

Yes I have two more apps and all of them authenticates against shibboleth. This problem is driving me crazy.

Thanks,
Gioele

Hi Gioele,

please note that the shibboleth authentication in GeoNetwork does need
the module mod_shib in apache for performing the needed redirection toward the
IdP. This is also stated in the page you referred
https://github.com/geosolutions-it/core-geonetwork/wiki/Shibboleth-setup-
on-2.10.x

Please make sure that mod_shib puts in the needed headers when forwarding the
user request to the shib.user.login service.

   Cheers,
   Emanuele

Apache has mod_shib and other apps in tomcat works like a charm with shibboleth.
Apache uses ajp connector to communicate with tomcats and for passing the IDP attributes (on the same tomcat another app is working without problems).
Can I modify the shib.user.login service and add a log function to it? How can I do this?

Thank you,
Gioele

Hi Gioele,

The service does nothing, as you can see here

https://github.com/geonetwork/core-
geonetwork/blob/2.10.x/web/src/main/java/org/fao/geonet/services/login/ShibLogin.java

The authentication flow is driven by Spring, so you should give a look to
https://github.com/geonetwork/core-
geonetwork/blob/2.10.x/web/src/main/java/org/fao/geonet/kernel/security/shibboleth/ShibbolethPreAuthFilter.java

I guess you only need to add this line

    log4j.logger.geonetwork.auth = DEBUG

to your log4j.cfg file.

I have started tomcat in remote debug mode and I discover that Geonetwork doesn't receive the session attributes from the Service Provider.
It is strange because another app in the same tomcat receive all the attributes.
I continue to investigate and will warn you when I find something.

Yes I have. In debug mode I found that the request object is empty, at least it not contain any attributes as if they are not received by tomcat (even if it receives for other apps).

The method that fails (it return null) is MinimalUser.create() in the ShibbolethPreAuthFilter class (Line 92) because it took the request, as first parameter, that hasn't the required attributes send from service provider.

In the apache config I had not added the directive "ShibUserHeaders On" ( in the document on github was not expected ).
Now it works.
