Single Sign On

[monty]

I'd love to see the ability to host many pligg sites AND allow users of the site to log in using the same username and password.

I don't believe this is doable now, but maybe there's a code tweak that you guys know of that would allow for this.

On central User repository for many pligg sites would be awesome.

Let me know. (i'm going to work on skinning pligg and when I do I'll post a howto plus the skin on my blog...once I get that up as well ;P

thanks!

I proposed this idea to the developers over a month ago, but the majority of developers told me that they would not want this because they want "their own members". This could be done if Pligg transitioned to TypeKey authorization (explanation below). I thought it was a bit of a selfish perspective to not let users jump from one site to the other with ease.

Here's my proposal that I gave for the developers to look over:
TypeKey is a user authentication technology I first saw being used in the latest version of Geeklog (one of my favorite CMSs) that was released late last year. The system works by creating a central user database for multiple sites to log in with. Much like how Gravatar lets you take your icon from one site to another, TypeKey lets you log in to several sites using the same credentials. If integrated with Pligg users would be able to log in to any Pligg site with the same credentials. So if you are signed up for an account with Pligg.com you can log into Shakk.us with the same username and password. Currently TypeKey is being used for Blogger and LiveJournal accounts, which means that if a user has a Blogger account they could log into a TypeKey enabled Pligg site with their Blogger username and password.

The big reason I would like to have this feature built into Pligg is so that we can have a centralized user database. That way we could share users between all Pligg sites and make it more convenient for users to log in to sites without having to go through the registration process over and over again.

I'd also love to see that feature.

while I understand your request to have single sign on across the pligg community I also agree that your request is a bit extreme.

what I'm suggesting it single sign on for the pligg site that any user maintains.

so if I run 4 pligg sites I want to allow my users single sign on to just those 4 pligg sites.

that's a bit more realistic than a communal pligg user base. the greater concern there is data corruption and integrity. who's the controller, etc. who owns the data, etc.

I don't think my request is too far fetched.

Monty,

I was one of the 'selfish' ones who objected to the 'global typekey' solution. That being said, I believe your idea is a good one.

Pligg is currently setup to look at one database for everything including votes, comments, users, etc. So Pligg would have to be modified to look up user data separately. I would like to think this is possible.

Anyone?

I don't know how to do it, but couldn't you use one database for all 4 sites and give each a different table prefix except the user table. Not sure how that would be done in the code, but I have seen it done somewhere else. (can't remember where now, not with pligg but another cms). As long as the user table is the same accross the different sites it should work fine. (no extra fields for one site or another). It could be done I'm sure.

[monty]

thanks for the replies. I would think it wouldn't be a huge issue.

just wanted to know if anyone has done it OR knew that it was for some odd reason a extra difficult task.

I haven't looked at one line of code for pligg yet.

just making sure it's something I could use and I believe it is.

sounds good. thanks for the replies!

That's what I meant as well. I would find this very useful.

this came up a while ago at drupal, here's a link to the most succint review of optiosn and alternatives: drupal single sign on topic
(note that you should follow the whole thread, as users reviewed just about every option out there beyond the top five or so)

also, this post links to the drupal single sign on module, which, "Enables "Single Sign-Ons" between related Drupal sites on one server with a shared database"

perhaps that code will help somebody...

however, i think that the sxip module (for drupal) will probably be better long haul, as it is supported by the IETF...

I would like to see this, as well. I want to allow single sign on across multiple apps like phpBB, MediaWiki and Pligg on the same domain. How about Yahoo!'s BBAuth? Anyone tried that approach yet?
