Hello.

Are you sure you followed the right steps to perform the upgrade?

Do you have any customization on that server?

mtsiak

We cannot seem to find any misfunctionalites for now. User's profiles are ok, documents, workflows work. our amps work.

For more info, below i am attaching parts of our configurations.

   <endpoint-url>http://mydomain:8080/alfresco/api</endpoint-url>
   <identity>user</identity>

</endpoint>

We have set an apache2 as a proxy on 80, and 443, and external SSO authentication.

/etc/apache2/sites-enabled/mydomain-ssl.conf
Listen my.ip:443
<VirtualHost my.ip:443>
   ...
   ProxyPass /alfresco ajp://127.0.0.1:8009/alfresco connectiontimeout=1200 timeout=1200
   ProxyPassReverse /alfresco ajp://127.0.0.1:8009/alfresco
   ...
  <Location /alfresco>
     AuthType shibboleth
     ShibRequireSession On
     require valid-user
     RequestHeader set X-Alfresco-Remote-User %{uid}e
   </Location>
</VirtualHost>

The connectors

tomcat/conf/server.xml
<Connector port="8080" URIEncoding="UTF-8" protocol="HTTP/1.1" connectionTimeout="20000" 
   maxHttpHeaderSize="32768" />

   allowUnsafeLegacyRenegotiation="true" 
   maxHttpHeaderSize="32768" SSLProtocols="TLSv1" />

Hope to enlight you. How can we find how this request is produced?

mtsiak

Also they all seem to come from the same authority. We use this authority for our tests, and the errors are still printed, although we are not doing something with this user.

mtsiak

we restarted apache2 and tomcat, have not connected with this user and we get still the same error!

You can use the following sample file as a reference in order to check if you have all the endpoints set
