If you follow that path fully, even the !ldb check is redundant.
ldb_dn_new will deal with ldb==NULL fine and return NULL.

By the way, our convention is to add a signed-off-by (git commit -s)
flag to patches. Can you do that?

You might also internally contact Simo Sorce. He has put in those
checks ages ago, maybe he has some comments on your patches.
