Hi,
I’ve just started trying to play around with RT4. I also installed RT::Authen::ExternalAuth 0.08_02. LDAP authentication is configured and it works fine. However, I’ve a problem with rt-crontool. Running it will result in the following error:
Modification of a read-only value attempted at /usr/lib/perl5/site_perl/5.8.8/Net/LDAP/Constant.pm line 13.

If I remove RT::Authen::ExternalAuth from RT_SiteConfig.pm, rt-crontool runs fine.
Is this a known issue? Any help to solve this problem? Thanks.

Ok, problem is resolved.
It seems to be an issue with Net::LDAP 0.4001 (perl-ldap-0.4001.tar.gz). Patch available in Human Verification.
rt-crontool runs now.
