Stuck at "Block invalid SAML response"

Jump to solution

Hello,

 

I'm trying to configure SAML authentication but I can't get passed the reponse validation from my idp. 

 

Would anyone have a suggestion about what kind of debug I can do to understand what's happening under the hood ?

In mwg-core-auth.debug.log I can see : 

 

[2021-11-18 03:38:20.448 +01:00] [3875] AuthServer (552, 192.168.6.85) URL: https://novaproxy.trustisland.com:9090/mwg-internal/de5fs23hu73ds/plugin?target=Auth&reason=Auth&set...
[2021-11-18 03:38:20.448 +01:00] [3875] AuthServer (552, 192.168.6.85) Configuration: Authentication server - Cookie check Connection: 0x7f44dc0e6920 RR: 0x55b0f8073200
[2021-11-18 03:38:20.448 +01:00] [3875] AuthServer (552, 192.168.6.85) Added authentication method: AuthServer https://$<propertyInstance useMostRecentConfiguration="false" propertyId="com.scur.engine.system"/>$novaproxy.trustisland.com:$<propertyInstance useMostRecentConfiguration="false" propertyId="com.scur.engine.system.proxy.port"/>$/mwg-internal/de5fs23hu73ds/plugin?target=Auth&reason=Auth&setCookie=true&cookiePrefix=MWG_Auth&cookieSize=16384&ttl=360&Persistent=yes&ip=yes&url=aHR0cHM6Ly9ub3ZhcHJveHkudHJ1c3Rpc2xhbmQuY29tOjkwOTAvbXdnLWludGVybmFsL2RlNWZzMjNodTczZHMvcGx1Z2luP3RhcmdldD1BdXRoJnJlYXNvbj1BdXRoJnNldENvb2tpZT10cnVlJmNvb2tpZVByZWZpeD1NV0dfQXV0aCZjb29raWVTaXplPTE2Mzg0JnR0bD0zNjAmUGVyc2lzdGVudD15ZXMmaXA9eWVzJnVybD1hSFIwY0RvdkwzbGhhRzl2TG1aeUx3LCwmcm5kPTE2MzcyMDMwOTkuODQ0ODU4NzIy&rnd=1637203100.473112980
[2021-11-18 03:38:20.448 +01:00] [3875] AuthServer (552, 192.168.6.85) Authentication didn't return values, failure ID: 4, authentication failed: 0

but that's not enough... I think I need to get some logs about the SAML parsing engine but I can't figure where to find it.

 

Thanks !

Hello,

"Block invalid SAML response" means we get the SAML Response from the IDP, but fail to parse it. So something in the SAML Respose does noch match the configuration done on the Web Gateway.

Are you able to put the "Authentication.SAML.Error" property into the block page? It should give a hint on what is going wrong.

Many Thanks. Solving the problem was so easy once I got the error message... That was so obvious 😉

(The problem was about the signature certificate from my IDP..)
