Gisle Vanem:
Patch for ldap.c under Windows. It works with wldap32.dll as supplied with Win-98/ME/2000/XP, so no extra .dlls are required. I've mostly tested it against Verisign's ldap server. Added code in the case there are to many responses (rc = LDAP_SIZELIMIT_EXCEEDED) and print only those we got. E.g. curl ldap://directory.verisign.net/?cn,display-name,mail,info?subtree?(cn=*Nelson*) will print the first 10 results. My only problem with it is that ldap_search_s() fails with "filter error" when CURLDEBUG is defined ?! Maybe someone can spot the error.
