After spending several hours investigating how search functionality in User Manager works and doing some "shaman dancing" around it, I ended up with a solution that requires to override a standard Sitecore.Security.Accounts.UserProvider and change its method called "GetUsersByName". As it turned out, search functionality of User Manager calls the GetUserByName method when one searches for a user.
This is how it looks:
namespace Sitecore.SharedSource.Security.Accounts
{
public class UserProvider : Sitecore.Security.Accounts.UserProvider
{
protected override IEnumerable GetUsersByName(int pageIndex, int pageSize, string userNameToMatch)
{
return FindUsers(pageIndex, pageSize, userNameToMatch);
}
protected IEnumerable FindUsers(int pageIndex, int pageSize, string userNameToMatch)
{
Assert.ArgumentNotNull(userNameToMatch, "userNameToMatch");
IEnumerable users = null;
string userWithNoWildcard = StringUtil.RemovePostfix(Settings.Authentication.VirtualMembershipWildcard, StringUtil.RemovePrefix(Settings.Authentication.VirtualMembershipWildcard, userNameToMatch));
if (Regex.IsMatch(userWithNoWildcard, @"^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$"))
{
users = findByEmail(pageIndex, pageSize, userWithNoWildcard);
}
else
{
users = findUsername(pageIndex, pageSize, userNameToMatch);
}
return users;
}
protected IEnumerable findUsername(int pageIndex, int pageSize, string username)
{
int total;
return new Enumerable(delegate
{
return Membership.FindUsersByName(username, pageIndex, pageSize, out total).GetEnumerator();
},
delegate(object user)
{
return User.FromName(((MembershipUser)user).UserName, false);
});
}
protected IEnumerable findByEmail(int pageIndex, int pageSize, string userToMatch)
{
int total;
return new Enumerable(delegate
{
return Membership.FindUsersByEmail(userToMatch, pageIndex, pageSize, out total).GetEnumerator();
},
delegate(object user)
{
return User.FromName(((MembershipUser)user).UserName, false);
});
}
}
}
That's it! Simple enough, isn't it.
Thanks to Alex Shyba who helped me with some useful code!
After compiling the code and moving a dll to the /bin folder, don't forget to change a reference in web.config file to point it to a new UserProvider class.
<userManager defaultProvider="default" enabled="true">
<providers>
<clear />
<add name="default">
<x:attribute name="type">Sitecore.SharedSource.Security.Accounts.UserProvider, YOUR_DLL_HERE</x:attribute>
</add>
</providers>
</userManager>
<userManager defaultProvider="default" enabled="true">
<providers>
<clear />
<add name="default">
<x:attribute name="type">Sitecore.SharedSource.Security.Accounts.UserProvider, YOUR_DLL_HERE</x:attribute>
</add>
</providers>
</userManager>
For those who consider this so easy so that it's now worth to create a VS project I've built a ready-to-go Sitecore package with a dll and include file inside. Just install it and give it a try ;).
This is a Sitecore package.
Enjoy!
