Apologies to the creator of this script for not giving credit but I've no idea where I sourced it from. It's been in the toolbox for a while.

This iterates through all databases and lists the orphaned users by database, along with the drop command to remove them. There may be a neater/newer way of handling this but this appears to function correctly on 2005-2012.

DECLARE @name nvarchar(128)

        [user_name] nvarchar(128) NOT NULL,
        drop_command_text nvarchar(200) NOT NULL
        )

Find orphaned users
I read somewhere here on stackoverflow that using NuSoap is not a good idea and its dead. If it is, what is the best possible solution to create WSDL files. I was just nusoap just for creating wsdl files and I never got the webservice to work
