So I just installed Fresh version of OpenBSD.
I have now tried this three times, and everytime it fails at this step.

After "# bash iRedMail.sh"
I follow all the steps in the guide, and it errors as follows on terminal

Couldn't install openldap-server-2.4.48
<< ERROR >> Installation failed, please check the terminal output.
<< ERROR >> If you're not sure what the problem is, try to get help in iRedMail
<< ERROR >> forum: https://forum.iredmail.org/

Any help? Please?
