Re: [PATCH] Add an ldapoption to disable chasing LDAP referrals

Hey Peter,

You are correct, it is the same as the referrals option in pam_ldap. It's
also the -C (sometimes -R - it seems ldapsearch options are pretty
non-standard) option in ldapsearch.

As far as I'm aware you can't pass this in an LDAP URL, primarily because
this never gets sent to the LDAP server. The server always returns an LDIF
with inline references, this just determines if you chase them client side
or just list them as is.

I could be missing something here, but using:

ldapreferrals={0|1}

Would require a three state type, as we need a way of not interfering with
the library defaults? To 'enable' the new behavior here using a boolean you
would need to set ldapreferrals=false - which with the normal way of
dealing with config booleans would alter the default behavior if the option
was not specified.

How do you feel about:

ldapdisablereferrals=(0|1)

Cheers,
James Sewell
