Membership wrapper - Sitefinity - General Discussions

I'm having a major issue with the Membership wrapper.

First, at initial login, the membership wrapper calls GetAllUsers(). This seems like a big performance issue, imho, when I have a user base of over 10,000.

Second, and this is the MAJOR problem. Apparently, the wrapper attempts to convert the ProviderUserKey to a GUID for some reason in the UserWrapper.CopyFrom method. My ProviderUserKey is not a Guid, and it's not required to be a Guid by the Membership provider model. Is there any work-around for this? This is a major show-stopper for me.

Hi Stephen Long,

The problem with the GUID is that internally our User object uses a GUID as Id property so we have to count on the fact that the ProviderUserKey is a GUID as well. The only solution we could come up with is to convert the Key to a GUID via some algorithm like MD5. We will investigate the possibilities and will try to find a workaround for this problem.

Kind regards,

Hi,

Is there any update to this? I too have implemented my own membership provider with 20K users, is there not a way to configure Sitefinity to page the users. The GetAllUsers method is designed for paging.

Also, I too have users which are not keyed by GUID, I was think of creating a Cache of key to GUID everytime I get a user by username. How did you solve this problem in the end?

Thanks,

Stu

I'm also looking for an update to this as I've just found the same 2 problems when implementing a customer provider.

I've got the error converting to a GUID which is an annoyance but I can work around it but I'm more worried about calling GetAllUsers on login. In some of our deployments we could be talking about huge numbers of users returned by the GetAllUsers method. I can't understand why this method is being called to process a login.
