Hmm, it seems that ldap_url_search is no longer available in 
OpenLDAP 2.1. So far I've never tested python-ldap with OpenLDAP 2.1.

You have two options:

* Use OpenLDAP 2.0.x to build python-ldap against that (see
   parameters library_dirs and include_dirs in setup.cfg to
   specify a separate OpenLDAP 2.0.x directory you used for
   OpenLDAP 2.0.x's ./configure --prefix)

* Remove any reference to ldap_url_search in
   Modules/LDAPObject.c. web2ldap does not use this function.

Ciao, Michael.

Anyone having any objections against removing methods url_search*()?

Anyone really using it? If yes, we could easily reimplement it
later with help of module ldapurl. The only issue would be that
ldapurl needs Python 2.x (not compatible with Python 1.5.x).

Ciao, Michael.

The only objection I have is that it really helped me to learn how to
work with an LDAP URL.  I needed to use URLs to configure exim to pull
data from LDAP, and I was having trouble using 'ldapsearch' -- it
didn't like the URL no matter what I gave it.  For me it was a
valuable tool.

Though if OpenLDAP 2.1 doesn't have the function, then that's a real
strong argument for removing those methods (at the very least when
compiled against OpenLDAP 2.1).

Personally I don't consider compatibility with python 1.5.2 a
significant feature.  2.0 was released a long time ago, by internet
standards.

How about practicing with the module ldapurl? It has more features=20
anyway. And it can construct LDAP URLs from search parameters with=20
method unparse().

Well, another strong argument is that there's no one actively=20
maintaining the C module part under Modules/. Therefore I'd be=20
glad to keep it as short as possible.

Ciao, Michael.

How?  The documentation is pretty sparse.  (I guess I could read the
source, though, and then I would say "Ok")

http://python-ldap.sourceforge.net/doc/python-ldap/module-ldapurl.html
http://python-ldap.sourceforge.net/pydoc/ldapurl.html


If the ldapurl module does everything that the current url_search
methods do, then there is no compelling reason to keep the latter
around.

It parses and unparses LDAP URLs and is designed to be completely=20
independent from module ldap.

Some sample code for parsing a LDAP URL:

 >>> import ldapurl
 >>> ldap_url =3D=20
ldapurl.LDAPUrl('ldap://localhost:1389/dc=3Dstroeder,dc=3Dcom?cn???bindna=
me=3Dcn=3DMichael%2cdc=3Dstroeder%2cdc=3Dcom,X-BINDPW=3Dsecret')
 >>> # Using the parsed LDAP URL by reading the class attributes
 >>> ldap_url.dn
u'dc=3Dstroeder,dc=3Dcom'
 >>> ldap_url.hostport
'localhost:1389'
 >>> ldap_url.attrs
['cn']
 >>> ldap_url.filterstr
u'(objectclass=3D*)'
 >>> ldap_url.who
'cn=3DMichael,dc=3Dstroeder,dc=3Dcom'
 >>> ldap_url.cred
'secret'
 >>> ldap_url.scope
0

Some sample code for the other way round:

 >>> ldap_url =3D=20
ldapurl.LDAPUrl(hostport=3D'localhost:1389',dn=3Du'dc=3Dstroeder,dc=3Dcom=
',attrs=3D['cn','mail'],who=3D'cn=3DMichael,dc=3Dstroeder,dc=3Dcom',cred=3D=
'secret')
 >>> ldap_url.unparse()
u'ldap://localhost:1389/dc=3Dstroeder,dc=3Dcom?cn,mail?base?(objectclass=3D=
*)?bindname=3Dcn=3DMichael%2Cdc=3Dstroeder%2Cdc=3Dcom,X-BINDPW=3Dsecret'

That's pretty much all it does. Note that you don't have to=20
specify all the class attributes. There are reasonable defaults=20
assumed. And who and cred maps to None if not specified. See the=20
tests at the bottom of ldapurl.py for more examples.

Advice: For security reasons you shouldn't specify passwords in=20
LDAP URLs unless you really know what you're doing.

Ciao, Michael.

I removed method url_search from LDAPObject.c.

We can reimplement that in the Python wrapper class=20
ldap.ldapobject.LDAPObject if there's request.

Ciao, Michael.
