Thread:Project:Support desk/Restrict users from Group

Hello Team, I had installed Mediawiki-1.18.2 with Mantisbt-1.2.10 integration. Users are logged in to Mantis and can links to Mediawiki through Wiki(TAB). Mediawiki is using Mantis authetication Single-Sign-On(SSO). So Mediawiki is using Mantis Database and for Database we are using MySQL-5.3. There are 3 project Java,PHP,Support. Now we want users from Java Project can edit only to Java Project Pages and PHP & Support Project users should only be able to read the Java Project and not able to edit it.
