Hi there,
I've deployed an OpenLDAP using the security options recommended by my cybe=
rsecurity team:
- olcSecurity: ssf=3D256
- olcLocalSSF: 256
- olcRequires: authc
- olcDisallow: bind_anon
- olcTLSVerifyClient: try
So essentially right now is required to use LDAPS in order to bind to the O=
penLDAP server. Otherwise a Confidential error will appear since TLS SSL Ha=
ndshake is not possible. Well, this is the expected behavior.
All the software of the environment works flawlessly using the SSL Certific=
ates through LDAPS SSL except Bind DLZ. I could not find the way to configu=
re it to use SSL.
The Bind DLZ used is the one compiled with the BIND 9.16.6 (Stable Release)=
from the SUSE 15 SP2 repository.
Could anybody help me?
Thank you so much.
Regards.
P Please consider the environment before printing this e-mail.
