I was debugging some random issue involving pursuing referrals, and found a note on this page:

http://etutorials.org/Server+Administration/ldap+system+administration/Part+...

And it makes this assertion:

By default, the ldapsearch tool shipped with OpenLDAP 2 prints information about referral objects but does not automatically follow them.

...

To follow the search referral, give the -C (chase referrals) option when you invoke ldapsearch:

And, by golly, it worked!

I'm using the openldap-ltb-2.4.39-2.el6.x86_64 RPM package, and that package's manpage and 'ldapsearch --help' show nothing about this option.

Is this a supported option? Is it documented somewhere officially? I couldn't find it after a quick search...
