But ldap-search expects ldap-ldapsearch-args to be at least what default
value is, to be able to parse the output (btw, "-LL" was there since
"forever", which is 20 years in this case; it's just the third L which
was added recently, to exclude ldif version from the output). Also,
default value can change along with ldap-search internal changes. So if
you want to let-bind it, you should merge in your additional args, not
replace them.
However, I don't see why you would want to let-bind it:
- -H: Why don't you use host parameter?
- -x: just pass 'auth = simple
- -tt: already in ldap-ldapsearch-args
Even more, I'd say that the user should set ldap-host-parameters-alist
according to his/her setup, and you should not mess with ldapsearch
arguments at all. Like:
(setq ldap-host-parameters-alist
'(("ldap://example.org"
auth simple
auth-source t)))
Then just invoke:
(ldap-search "mail=.." "ldap://example.org" '("userCertificate"))

Without -LL(L), the parsing code works incorrectly, and this case
"worked" before only by coincidence.
HTH,
