CA request - Windows Server 2012 - Subject Alternate Name

Hi,
 
On 2008 R2 SubCA I used .inf file to create certificates with SAN. I used the following extension:
 
[Extensions]
 2.5.29.17 = "{text}"
 _continue_ = "dns=name.domain.com$dns=othername"
 
This does not seem to work on a 2012 SubCA. Is there any changes in how to get SAN in the certificate?
 
Regards,
