You should use the Net::LDAP (perl-ldap) package. Make sure you use page 
mode access (pages are ~1000 entries for Windows 2000 and ~1500 for 
Windows 2003) and process each record in a call back. If you set the 
line wrap in the Net::LDAP::LDIF  object   you use to write the output 
you should get the results you want.

I have production code using this technology that will process over 
120,000 records in less than 15 minutes from a moderately loaded Active 
Directory. So this should be good enough for what you want.
