guys, it’s true. this is still not yet tested with WordPress 3.

though i suspect perhaps any problems have something to do with the new salt definitions in wp-config.php – so i would start by making sure all those are consistent across all sites you’re trying to get unified login working with.

also, it’s possible that all this can now be achieved using the new multisite features merged/built into WP 3.0 – again untested.

so please, test away, and share any experience you’ve had getting this working with WP 3.0.

i’ll be sure to write a new post or update this one once i get a chance to test things on my own setup.

I have this scenario:

I have a site (siteA.com) and a wordpress (siteB.com). In siteA.com users can register and each time one is registered it adds the same user (using curl) on siteB.com (wordpress).
I need that when a user is logged in siteA.com it is automatically logged in siteB.com. They have different databases and domains. Is this possible? How ?

Is there a possibility this could work in Mu/3.0 Multi-site? has it been tested yet?

did you try disabling all non-related plugins? does it work for some users and not others? maybe try resetting their passwords, see if that solves it. also, check that these users have all the proper permissions – which must be setup correctly and individually for each site in a multi-WordPress setup. Oh, and try creating a new user in mutli-site mode to see if you can log in with that. It might be a problem with old accounts that used the old method of authentication and their old passwords no longer work with new versions of WP. Otherwise, disable the multi-site setup temporarily and test whether these users can log in so you can know for sure that it happens only in multi-site mode.

Thanks for this post. I kept getting the permissions error until I edited the capabilities.php file and that seemed to solve the problem.

Everything seemed to be working fine, but then a few users emailed me saying they weren’t able to log in to the main site anymore. I tried their logins, but it just kept going right back to the login page instead of going to the admin. However I was able to log in fine with my own username. I thought maybe they needed to clear their cookies but that didn’t seem to help. Do you have any ideas why certain people would have trouble logging in but not others?

yes, but permissions for each user (wp roles and capabilities) are set individually for each site (even though it’s integrated).

so, on one site, you might have admin priviledges, but on the other site you are just a regular user.

that is what i think the problem is, in this case.. the user’s permissions are out of sync.
