問題
Browsing through the UI after installing third-party SAML SSO for Confluence display problem will be visible.
環境
Confluence with SAML SSO for Confluence
診断
Checking the HAR file 400 Bad Request HTTP errors will be visible.
If you receive this error frequently, the best thing to do is to delete the Cookies for that particular domain.
Let us say, if you are receiving this error when you visit any page on say, example.com, then you should delete all the Cookies of example.com from your browser’s cache.
原因
Header size is too big for certain requests. Increasing the value on Tomcat should help in this case.
ソリューション
Increase or add "maxHttpHeaderSize" size to "32768" in used connector in the <Conflence-install>/conf/server.xml like this:
<Connector port="8090" connectionTimeout="20000" maxThreads="200" minSpareThreads="10" enableLookups="false" acceptCount="10" URIEncoding="UTF-8" /><Connector port="8090" connectionTimeout="20000" maxThreads="200" minSpareThreads="10" enableLookups="false" acceptCount="10" URIEncoding="UTF-8" maxHttpHeaderSize="32768"/>
