Wordpress 3 Network Cookies Broken

[scottsturges]

I have two blogs set up on my site with different domain names...
Lets call them: example.com and example.org

Example.com is the default, and example.org is a secondary.

Logging into example.com works, however when logging into example.org, the cookie is set to example.com, and therefore causes the login to fail making it impossible to access wp-admin.

I think, that before this WP3 goes live, cookies should be set to a current domain basis, rather than to the default domain.

Does anybody have ideas as to what would fix this.

Note, I assigned this to a high priority, as it can cause users to be unable to administer their blogs, completely blocking access to the site.

Are you using multisite? If so, Are you using a plugin to allow the multiple domains?

Otherwise, Did this setup work in WordPress 2.9.2?

No plugin, just the built-in multisite.
It used to work many versions ago on WPMU, but I haven't tried the same one until ver3.

I can access both sites fine, I just can't admin one of them.

I believe (I'm not 100% certain about -any- Multisite functions) that Domain mapping was removed from core during the merge to WordPress 3.0, Subdomains and Sundirectories are supported.

Perhaps have a look at this plugin and see if that solves your problems? ​http://wordpress.org/extend/plugins/wordpress-mu-domain-mapping/

Setting to Future release pending someone who knows what they're talking about coming along :)

Replying to dd32:

Domain mapping is a plugin and was never part of MU core. In MU, if you edited the siteurl and home as the reporter has done, you would get the same result.

If an admin wants to do this, then use one of the domain mapping plugins. Per multiple discussions on this subject in IRC & meetups, multiple domain support is plugin territory.
