Open Source Document Management

Just Downloaded LogicalDoc-6.3.1-tomcat-bundle.zip and copies its war file into a tomcat installation in ubuntu, the tomcat runs and the logicaldoc runs, but I can not proceed to the setup because the username and passwords are dinied.
Is there a different installation manual for this release,
Is there another place to set up the user and pass other than conf/tomcat-users.xml, please help

The initial username is admin and password is admin

After you added user to your tomcat-users.xml you must restart tomcat.
See otherwise the tomcat bundled with the LogicalDOC CE distribution, it has all the users already configured in the tomcat-users.xml file
