If you are using LDAP (AD) as the authorization method for TAC and SVN and use the same account for both, the project fails to open in Talend Studio 6.4.1 with the following error:
Caused by: org.tmatesoft.svn.core.SVNAuthenticationException: svn: E170001: Authentication required for <http://192.168.0.83:80> SVN Server
Studio cannot get the authorization of SVN, which is caused by the configuration of LDAP.
This is a known bug. Install Patch_20171019_TPS-2211_v1-6.4.1 to resolve it.
