Accessing AD from UNIX machines

[sayali k]

Hi all,
  I wanted to know some programming technique using which it would be possible to access the Active Directory users/groups and other details from UNIX machine. 
  I would like to write a small C/C++ program which would do this, like in case of Java, JNDI can be used to connect to AD using LDAP and then access the objects in AD.
   
  Thanks a lot for all the help I am getting here.
   
  Regards,
  Sayali
