It's not essential that you find them all, but it would be nice to at
least find the more obvious ones. I actually don't think there are
very many of them. There are less than 90 calls to
ldb_msg_add_string() and it is fairly clear from a git grep that most
of them are not for a DN.
Each developer tends to have different habits, but when I am looking
for something like this I tend to do the git grep in emacs, and use
the "next hit" key to take me between them. It usually only takes a
few minutes to find the ones that need fixing.
Don't worry too much if you don't find them all, and if one of them
looks too tricky to change then its OK to leave it out of course.

That's reasonable for now. We don't really have a good way of handling
internal db errors well beyond DEBUG() messages.

Interesting! I think you should investigate this and find out why. The
fix is definately not to add an invocationId. It probably means there
is an existing bug in a different function in the code that your patch
happens to reveal. You should either use gdb or DEBUG() lines to work
out what in samdb_ntds_invocation_id() is failing. There are 4
possible calls to "goto failed" in that function that could be causing
the error. You need to work out which one it is, and then work out why
it is happening.

Thanks for the git repo, that is much easier to work with than patches.

learning git is a bit of a journey :-)
Don't worry about what branch it is on for now. I can look on the cd1
branch without problems.
