[Samba] wbinfo question

[Markus Moeller]

I have a domain whose netbios name is WIN2003R2 and the Kerberos domain name 
is win2003r2.home. Using wbinfo I get:

wbinfo -D WIN2003R2

Name              : WIN2003R2
Alt_Name          : win2003r2.home
SID               : S-1-5-21-1828870822-1098772068-2592627279
Active Directory  : Yes
Native            : Yes
Primary           : Yes
Sequence          : -1

Where in AD is the Alt_Name stored ?  Can I access this info also via an 
ldap call ?

Thank you
Markus
