We're using Active Directory for membership and in a Rest Extension when calling HttpContext.Current.User it is returning the currently logged in umbraco user rather than the currently logged in member..

I was wondering if anyone else had experienced this?

in a razor view using @Membership.GetUser().UserName it returns the logged in member

if I do this in code:

[RestExtension("InductionHelper")]
public class InductionHelper
{
    [RestExtensionMethod(ReturnXml = false, AllowAll = true)]
    public static string RegisterPolicyAgreement()
    {
        var memberName = Membership.GetUser().UserName;
        var someRandomVarName = ApplicationContext.Current.Services.MemberService.GetByUsername(memberName);

Membership.GetUser() is querying based on the currently logged in umbraco admin user in our override of get user:

public class CustomMembershipProvider : ActiveDirectoryMembershipProvider
{
    public override MembershipUser GetUser(string username, bool userIsOnline)
    {
        if (!string.IsNullOrWhiteSpace(username))
        {
            var result = (MembershipUser)HttpContext.Current.Session[username];

            if (result == null)
            {
                result = base.GetUser(username, userIsOnline);

                HttpContext.Current.Session[username] = result;
                HttpContext.Current.Session["recentUser"] = username;
            }

            return result;
        }
        else
        {
            return null;
        }
    }
}
