Firstly congratulations to developers of JMS2Win - clearly superior. As we plan deployment - some extensions conflict with others - so we are thinking of creating a blogging template, a videoshare template and a content template with the idea that the templates and all slave site stem from one master?

We however - need to have all users / jomsocial and k2 content along with some polling, discussion, etc extension replicated across the board -

is that possible - because i read that all extensions must be there in master - what if we want to install certain extensions in only one slave or in one template - but ensure that all sites have synchronized users / and jomsocial

Lastly -can we single sign on - where users are shared - please give alternatives if JMS cannot do single sign on

thanks a lot.

YES, all the extension must be installed in the master and it is not possible to install an extension in a slave site that is not present in the master.

The reason is very simple.
Only the master website contain the PHP code installed by the extension.
The slave site just make reference to something that must exists.

You can create slave sites that share the JomSocial and share K2.
JMS Multisites use sharing and NOT syncrhonization that suppose that you replicate data.
The sharing mean that the data is present only once (no duplicated data - no duplicated users, ...).

The single Sign-in is only possible on website using the same domain name. So you can have slave site with different subdomains or subdirectories.
If you are using different domain, the users will have to re-login with the same login and password. You can avoid that if you enable the "remember login" present in Joomla. This consists in saving the login and password in a cookie to avoid the users to re-enter them.

Yes> Thank yOu - Please clarify - You mention two options -

Sharing from same DB and also - installing in separate databases and separate directories - In both of them - is it SHaring only.

All sites have TLD which is same only subdomains and sub-subdomains are different - that means - even if I have different databases and installs in different directories - yet the single sign on will work?

thanks

TLD (.com, .net, ...) is not enought for the single sign-in.
You must have the same domain.tld where you can have different subdomain.SAMEDOMAIN.TLD or different SAMEDOMAIN.TLD/subdirectories.

The Single Sign-In is related to apache that only return the same session ID when working on the SAMEDOMAIN.TLD

Single Sign-In is related to the apache sessions ID and not to the directory where the site is located. You also need to have the MySQL "#__sessions" table that are shared.

DB is something else.
You can create website into the same DB or in different DB.
To verify the user access, you can share the MySQL tables in a same DB or in different DB. It is just most easier to share different MySQL table in a same DB. When sharing MySQL Table between different DB, you need a MySQL user that has enought privileges to share the MySQL table and also access the info.

I hope this is more clear.
