Configuring SSO with SSL

Question asked by chrisokelly on Apr 17, 2012
Latest reply on Apr 18, 2012 by chrisokelly
Hi,

We have been running on SSO and SSL for some time, recently we reinstalled, copying across config from the previous (4.0.b) installation to the new (4.0.d). I noticed that since the reinstall SSL had not been working, only showing the login page which worked fine for LDAP login.

In trying to fix this, I believe I have caused more problems then I have fixed! It originally appeared like it was going to be easy, I noticed that the share-custom-config.xml file in shared/tomcat/classes/alfresco/web-extension was missing, so I created one and copied in the SSO and Port Config sections from the sample.

Now we cannot log in at all! I have come across a few things and fixed them to try and solve this - firstly, in alfresco-global.properties the port was set to 443, although in tomcats server.xml the connector was on 8443. I changed the default ports to 8443 and restarted. Now it is telling me "unable to find valid certification path to requested target" which, from my reading, suggests the issue lies with our self signed SSL Certs not being trusted. I never set these up originally (it seemed to be automated by the quick installer from what I saw) however when I followed the instructions in the .txt file in alf_data/keystores The last step told me "keytool error: java.lang.Exception: Certificate not imported, alias <AlfrescoCA> already exists", confirming my suspicions this was already done (as SOLR has been running fine and I was sure that it uses SSL already).

some info about our setup-
/opt/alfresco-4.0.d/alf_data/keystore$ sudo keytool -list -keystore ssl.keystore -storetype JCEKS
Enter keystore password:

Keystore type: JCEKS
Keystore provider: SunJCE
