I am not sure what happened. I have many protals for testing.
I don't understand about the DNN membership system cross multiple portals. Does it all different portal have the same user account?
Why I ask this question is because when I create a new portal and I use the same administrator for convenient. But system will ask me to create a different account because there is already a the same account name exist!!
And other problem is I have several testing portals they have the same administrator. For example portal A and portal B both have a administrator account name Eric. (I create these portal long time ago.). One day, I think one of the testing portals doesn't need anymore. So I delete that portal (ex: I delete portal A). Then something happened!! I can't use Eric to login into Portal B. But other account about the portal B is no problem. Actually, I login as host account. I found the Eric still exist in Portal B's member list. But some data are incorrect. I check the database. It seems the user data for asp login was delete? (aspnet_Users and aspnet_Membership).
Does this the problem of the DNN system?
Is there more information for the member system I can reference?
Can the same account name exist with different portals? Will it have problem when I delete a portal that has the same account with other portal?
Could anybody help me about this issue?
