auto-login when user click link to my site from another site

[weblantis]

Hello,
I was hoping someone could help me with this.

I have 2 wordpress websites (abc.com and xyz.com). I have s2members installed on xyz.com. Is there a way for someone to automatically log into xyz.com whenever they click on a link to xyz.com from abc.com? This assumes:

- User is already logged into abc.com at the time of clicking the link (in my case the link actually resides on the wordpress backend).
- User already has Level 2 login access to xyz.com.

I want to set up this system so that a user can make comments on an xyz.com restricted page without needing to enter login details.

I found this:

http://wordpress.org/extend/plugins/dg-auto-login/

but I am not sure how to get it work.

Thanks,
Sher

Hi Eduan,

Thanks for helping out. I also came across this thread.

I am not sure if this will work because in my case, the people visiting my site (xyz.com) are likely to have dynamic ip addresses. I think the only IP address that will stay unchanged is of the abc.com server's ip address.
