[ldap] changing a bunch of ldap entries at once?

[Adam Williams]

I have a bunch of users that have a mail entry I want to delete.  As an 
example:

dn: uid=jdoe$,ou=Computers,dc=mdah,dc=mdah,dc=state,dc=ms,dc=us
mail: [EMAIL PROTECTED]
I know I can delete them one at a time with the following ldif for each 
user and run it manually

dn: uid=jdoe$,ou=Computers,dc=mdah,dc=state,dc=ms,dc=us
changetype: modify
delete: mail
mail: [EMAIL PROTECTED]

but is there a way to automate the process or globally drop mail: from 
every uid in the ou=Computers?
