You may prefer to look for some existing scripts/tools. For example, I have:
http://staff.telkomsa.net/~bgmilne/ldap/ldap-passwd.pl

which can work as a shell command or as a CGI. I currently use it in conjunction with the script:
http://staff.telkomsa.net/~bgmilne/ldap/find-ldap-expired.pl

which notifies my users by email that their passwords will expire.

Run 'perldoc xxx.pl' to see the documentation for each script.

You should probably compare the logs on the LDAP server for the two binds, and see if they differ. I suspect a difference introduced by shell quoting. I wouldn't use exec, but rather just call ldapsearch directly.

But, then, shell quoting, handling of spaces etc. are reasons to avoid shell scripting for serious LDAP work.
