I have wordpress setup running multisite with my main site on a subdomain eg. blogs.mysite.com which means all additional subdomain sites would correspond to urls like sub1.blogs.mysite.com, sub2.blogs.mysite.com etc.
What I actually ended up doing was pointing additional top level domains to the wordpress installation and editing database entries for each of the multisite entries to correspond with their domain. I have everything working pretty smoothly except for an issue trying to login from the additional sites.
I don't think a need domain mapping since I have each additional blog setup in subdirectories of the domains and not actually the roots so myothersite1.com/blog and myothersite2.com/blog are what actually end up pointing to the wordpress files. And except for the login issue everything is smoothsailing. Any ideas or suggestions?
I think this has something to do with the way the login cookie is set which is probably defaulting to my main site blogs.mysite.com. What would be a good approach at fixing this?
