Bug report: Expanding variables with filter default in LDAP context does not suppress error logging if LDAP attribute is missing.

Expected behaviour: Missing LDAP attribute does not throw an error. Example nologin = %{ldap:missingAttribute | default}

Hi!

We actually have a test for this, that tests this exact thing you are seeing, so I am bit wondering how this can happen. This test has been here since 2.4.0, and it passes with 2.4 all the time.

I even copypasted your passdb block as-is and I can't get error you're seeing, so there is something else going on. Can you please send me your full doveconf so I can test it properly?
