Hi
I have been making good progress on a project of getting a number of sites belonging to one organisation to share some components. However, an important one is CiviCRM. It is installed, and I can see all the screens etc. except that whenever I try to do something meaningful, like search for contacts, I get sent from the 'slave' site that I am working from to the administator of the master site and have to log in again. After this I sometimes get session errors generated by civicrm. However I don't get these if I first log out from the slave site and log into the master site.

Would you please give more details on the error.
Also provide the error message with line code and a very detailled scenario on how to reproduce it.

Also provide real domain name that you are using between the master and slave site.
Tell us also if you have share the users between the master and the slaves.
