At work, we use Rudder to take care of configuration automation.
Today, I was trying to update a small script that we use on all our SMTP gateways, which does an LDAP request.
That LDAP request needed to be updated and instead of connecting to 40+ servers, I made a new Directive in Rudder. Using a regexp, I was trying to replace:
With the help of https://regex101.com, I used this regexp at first:
But for some reason it wasn’t working, and I would get:
Error: Because the regular expression '\(objectCategory=group\)' still matches the replacement string
The explanation, of course, is that the regexp I used would still match the replacement line, which means that every time rudder ran, it would be applied.
Thank you rudder for saving my script 🙂
