create Document Library based on user template

it took me a while to figure out that the Lists.asmx web service doesn't support creating a document library based on user template, the only way to do it is via a customized web service.
the code for web service can be found at http://blogs.msdn.com/sridhara/archive/2008/06/07/getwebtemplate-web-method-does-not-return-addlist-web-method-does-not-recognize-my-custom-list-templates.aspx

In my code, I also need to check whether the docLib already exists which can be done via the standard Lists.asmx web service.

AD Distinguished Name and special character

I wrote a script to send out password expiration notifcations a while ago, recently I got told that some users didnt' receive their notification.
After looking into it, I realized that the OU structure got changed recently and some OU name contains special characters, in this case if you use GetObject("LDAP://"& DN) to get user Object, DN has to be encoded for special characters.
In my case, a '/' was causing the issue and has to be replaced with '\2F' (hex).
