It fails for me here:
IndexError: list index out of range

I test on 389-ds-base-1.4.4.4-20200804gitb1e4f5f2b.fc32.x86_64

I've retested on a clean machine and it is good now. I'm not sure what was wrong...
So please, discard my previous comment.

And the rest looks good! Feel free to rebase and merge. Ack :)
