So here are patch

  0001-Undo-suboptimal-fix-for-dn-line-parsing.patch

to back out my initial fix, plus *alternative* patches

  0002-filipp-Do-not-process-dn-entry-with-ldap-decode-attribute.patch

  0002-jschmidt-Do-not-process-dn-entry-with-ldap-decode-attribute.patch

Both fix this issue while keeping complete API stability.  Filipps is a
bit shorter, but IMHO harder to read plus slightly less efficient on
runtime, mine is a bit longer since it (partially) duplicates code.

Both give the same results, in particular independently of the setting
of `ldap-ignore-attribute-codings':

  (ldap-search "(uid=jeschmid)"
               "ldap://ldap.company.com"
               '("mail"))
  => ((("mail" "jens.schmidt <at> company.com")))

  (let ((ldap-ignore-attribute-codings t))
    (ldap-search "(uid=jeschmid)"
                 "ldap://ldap.company.com"
                 '("mail")
                 nil
                 t)
  => (("dn: cn=JENS_SCHMIDT,L=REGION,DC=COMPANY,DC=COM"
       ("mail" "jens.schmidt <at> company.com")))

  (let ((ldap-ignore-attribute-codings nil))
    (ldap-search "(uid=jeschmid)"
                 "ldap://ldap.company.com"
                 '("mail")
                 nil
                 t)
  => (("dn: cn=JENS_SCHMIDT,L=REGION,DC=COMPANY,DC=COM"
       ("mail" "jens.schmidt <at> company.com")))

Feel free to apply whatever you think appropriate.  Please on *emacs-29
only* (I haven't found how to mark that).  Then please close this bug.

Thanks
