For WP 2.8.1 and WPMU 2.8.1

I’ve found that this gets broken in 2.8…basically if I define

define(’COOKIE_DOMAIN’, ‘.domain.com’);
define(’COOKIEPATH’, ‘/’);

in wp-config I am unable to access wp-admin on one of my installs. I am actually logged in there but just can’t access the admin section. Removing those two lines lets me back into admin…

Yes, thats exactly how I test single login. Could you try using the capability hack that I use. Although the only difference I see in both is that Im specifying my capabilities table whereas the post you have used takes it off the settings given on the website. Also there are some other things which I have added in my capabilities. Please note that the post you are reading is for Wordpress 2.5. I think mine works well in 2.7 so you should add the additional lines I have given or try using the hack Iv used. You will have to mod it for your variables for table name.

In case it still doesn’t work could you paste the capabilities hack you are using along with the capabilities table name of your main site or table whose login you are using? the taffele site which suggests integration is already mentioned in my blog however it may work for 2.6 dunno about 2.7.

Hey Kiran,

How are you testing your single sign on?

Are you going to www.kochidaily.com/wp-admin/ to login?
And then after you have successfully logged in, do you go to www.kochidaily.com/jobs/wp-admin/ to see if you’re logged in there as well?

Also I noticed that you’re using a different capabilities hack than I am.

This is the one I’m using:

Sorry for the late reply was busy with my newborn son’s homecoming (In India the mother leaves for her parents home for delivery and returns only three months after the baby is born) Sorry for the late reply.

Also Id like to confess I’m not very good at programming its just that I just applied plain logic from various sites as mentioned to arrive at the above so I am not an expert. But if you still haven’t sorted it out.

Adrenalini - Is there any specific benefit for you for running different databases? If not merge them into a single one. And try it ( on a standalone WAMP or LAMP local server). It should work (I think!)

Ray- After modifying the capabilities file are you able to login with the main sites login in the other site? What version of Wordpress are you using? It has to work. Try clearing your cache it must be the issue.

Hi Kiran,

I tried your technique on our site.

I get the right cookie names, but the values are different for “LOGGED_IN_COOKIE” and “AUTH_COOKIE”.

Which means I still have to login to both WP blogs. No single sign on for me!

TEST_COOKIE is the only one with the same value.

Any idea why?

Hi! Thank you for the instruction. Still, it doesn’t quite suit me, because I’m using separate databases for blogs (domain.com uses one database, sub1.domain.com - another etc.).

Any ideas how to share auth cookies in such situations?
