Re: Large Searches

[David R. <d.r...@qu...>]

OK:

perl -v produces:
This is perl, version 5.005_03 built for alpha-dec_osf

uname -a prduces:
OSF1 tu01m2.qut.edu.au V5.1 732 alpha

and perl-ldap is:
perl-ldap-0.22

I am attempting to retrieve about 120 000 entries, retrieving 5
attributes, which are (just for an idea of size):
	
	uid		: typically 8 characters
 	mailUID		: typically 89 characters
	QUTmailbox	: flag 'yes' or 'no'
	mailboxQuota	: Integer, most cases is 10000
	cn		: Normal common names.

The script is an account maintenance script for our central mail system,
to manage the active IMAP accounts, just for a bit of context.

Thanks,
