The curl manual says:

Quote:

LDAP

If you have installed the OpenLDAP library, curl can take advantage of it
and offer ldap:// support.

LDAP is a complex thing and writing an LDAP query is not an easy task. I do
advice you to dig up the syntax description for that elsewhere. Two places
that might suit you are:

Netscape's "Netscape Directory SDK 3.0 for C Programmer's Guide Chapter 10:
Working with LDAP URLs":
http://developer.netscape.com/docs/m...csdk30/url.htm

RFC 2255, "The LDAP URL Format" http://www.rfc-editor.org/rfc/rfc2255.txt

To show you an example, this is now I can get all people from my local LDAP
server that has a certain sub-domain in their email address:

curl -B "ldap://ldap.frontec.se/o=frontec??sub?mail=*sth.frontec.se"

If I want the same info in HTML format, I can get it by not using the -B
(enforce ASCII) flag.

And if it turns out curl doesn't do the trick in your case, try "ldapsearch" from the standard OpenLDAP utils.

ldapsearch has an option to download attribute-values to a temp-file.
From "man ldapsearch":

-t Write retrieved non-printable values to a set of temporary files. This is useful for dealing with values containing non-character data such as jpegPhoto or audio.
