I am using code like this to list all users:

foreach (UserInfo ui in UserController.GetUsers(PortalId))
{
	// Sneakily get password
	MembershipUser thisUser = Membership.GetUser(ui.Username);
	string thisPwd = "";
	if( thisUser!=null) thisPwd = thisUser.GetPassword();
}

In DNN 4.7 this works fine. In DNN 4.8 exception "Bad Data" is thrown:

   at System.Security.Cryptography.CryptographicException.ThrowCryptogaphicException(Int32 hr)
   at System.Security.Cryptography.Utils._DecryptData(SafeKeyHandle hKey, Byte[] data, Int32 ib, Int32 cb, Byte[]& outputBuffer, Int32 outputOffset, PaddingMode PaddingMode, Boolean fDone)

   at ASP.JCshowUserDetails.__Render__control1(HtmlTextWriter __w, Control parameterContainer) in d:\DNN480\DesktopModules\phdcc.Data.View\JCshowUserDetails.ascx:line 24

Any ideas?

I have found out somewhat what was going on here:

The call to GetPassword() was failing for the account "admin".  When the password was reset then the code works OK.  The site was a new test one where the "admin" account may not have been used before.  I can't be certain - is the "admin" account created OK from scratch?
