Hi where can I ask for an extension of feature to be added in the next version because what I want to ask is that extension central auth be built into Mediawiki software because it is so hard to set up and would be easer if it was built in
Topic on Project:Support desk/Flow
That's not going to happen. Additionally making central auth built in probably won't reduce complexity (The fact it is an extension isn't really related very much to how hard it is to set up)
If you want built-in shared login across wikis, you could try using $wgSharedTables.
p.s. As an aside, much of the complexity of CentralAuth is related to using the $wgConf wiki-farm config system, which is something that is built into mediawiki.
hi! what do I enter with $wgSharedTables because my database setup is localhost and different database user and name and are hosted under different emails
It may not work in that case. You may have to use centralAuth instead
