Virtual list view problem
by Venish Khant
Hi all
I am using cpan Net::LDAP module to access LDAP entries. I want to
search LDAP entries using Net::LDAP search method. When I do search, I
want some limited number of entries from search result, for
this(searching) process I am using Net::LDAP::Control::VLV module. But
I get error on VLV response control. Please, any one have idea about
this error.

Error:* Died at vlv.pl line 50,
This is my example. I changed the font style of line 50
#!/usr/bin/perl -w
use Net::LDAP;
use Net::LDAP::Control::VLV;
use Net::LDAP::Constant qw( LDAP_CONTROL_VLVRESPONSE );
use Net::LDAP::Control::Sort;

dynlist overlay feature request
by Alexander 'Leo' Bergolth
Are there any plans to extend the dynlist overlays dynamic group feature
to return not the DNs of the matched entries but an attribute of the
entries?
This would be useful for defining dynamic groups based on posixGroup
(which need only the username, not the full DN) and populating them with
entries from posixAccounts.
If the dynlist-attrset could be extended by one parameter like:
dynlist-attrset <group-oc> <URL-ad> [<member-ad>] [<result-ad>]
... where the additional parameter specifies the attribute that should
be returned from the search results, a dynamic posixGroup could be
configured like that:
dynlist-attrset myposixGroup memberURL memberUid uid
with a search filter like that:
ldap:///ou=users,dc=local,dc=site??sub?(&(objectClass=posixAccount)(<searchfilter>))
I.e. "take the uid attribute of the matched entries and add them as
memberUid."
Could this extension be easily implemented?
Is there currently any workaround?
E.g. a way to dynamically add a memberUid to each posixAccount that
contains the same data as the uid attribute? If that works, a filter like
ldap:///ou=users,dc=local,dc=site?memberUid?sub?(&(objectClass=posixAccount)(<searchfilter>))
... could work.
Thanks in advance,

Using Arbitrary X509 certificates for LDAPS authentication
by Stephen Cartwright
Hi there,
Are there any restrictions on the DN or other attributes of
credentials used for LDAP authentication?
We are using grid credentials (X509 format) with DNs like this:
issuer= /C=CA/O=Grid/CN=Grid Canada Certificate Authority
subject= /C=CA/O=Grid/CN=host/somehost.somedomain.ca
When I use some grid certs (X509 format) I see this message in the debug
output from slapd:
connection_read(10): unable to get TLS client DN error=49 id=3
When I try to connect, I get this:
ldap_initialize( ldaps://somehost.somedomain.ca )
ldap_bind: Can't contact LDAP server
The openssl command to create a connection works OK:
CONNECTED(00000003)

And then make no other changes to the config other than pointing
everything to the new commands I can make a connection.
Any suggestions? Please advise.

smbk5pwd does not properly update sambaNTPassword and sambaLMPassword
by Scott Classen
Hello
I am running openldap 2.4.18 (BDB 4.8.24). Both of which I compiled
from source.
I compiled smbk5pwd with support ONLY for samba. I am using the samba
that is distributed with CentOS 5.3 (3.0.33)
openldap does not crash or complain when it launches so I assume that:
moduleload /usr/local/libexec/smbk5pwd.la
is at least loading up the module correctly.
I have a user with the sambaSamAccount objectclass.
I have configured PAM to change the LDAP userPassword when invoked
from the command line with /usr/bin/passwd
The userPassword hash gets successfully updated and the values of the
sambaNTPassword and sambaLMPassword hashes are changed, but I am
unable to authenticate as a samba user against these hashes... and
they look sorta weird:
010000000000000090c9c94100000000
when I would expect them to look more "complicated" like:
552902031BEDE9EFAAD3B435B51404EE
Does this smell of a smbk5pwd bug/problem/misconfiguration or a samba/
PAM one?
Thanks,
Scott

Fwd: syncrepl inseard of back-perl ?
by Brett ＠Google
Hello,
I was wondering if there are any concrete examples of using syncrepl
to monitor a slapd for changes, and perform some scripted operation if
the monitored data changes. I can think of several cases where this
might be very handy, where you want to run a script or custom business
logic, on receipt of some data being changed.
I have seen some examples in the 2.3.x days, where slurpd was used to
push changes to a back-perl script, which then did some custom
business logic and it did fill an very useful niche. I imagine these
post-slurp syncrepl days you could use the syncrepl protocol in a push
mode via a proxy to push changes at a back-perl instance to the same
sort of thing.
But perhaps using syncrepl directly might seem like a better option,
as this has been touted as a benefit of syncrepl, although i have not
seen any specific examples.. To this end, i am wondering are the
syncrepl client parts of slapd usable outside the context of the slapd
binary? Has anyone tried this and has any examle code they are willing
to share ?
Cheers

PHP: issues managing the password, what is wrong?
by Alberto Moreno
Hi people, I doing a web interface that will request a username +
password, like squirrelmail i will contact my ldap server, this app
will run on Centos 5.3, php 5.3, this will be where my web pages will
be, the ldap server is running on Gentoo with ldap 2.3.43.
My current problem is with the password, I have found small app that
wants to compare the input of the password vs the ldap password this
will let us identify the user.
Well searching aroun, I found the crypt function but there is a
thing that I don't like it:
"The standard DES-based encryption crypt() returns the salt as the
first two characters of the output. It also only uses the first eight
characters of str , so longer strings that start with the same eight
characters will generate the same result (when the same salt is used)"
How can I deal with this note: 8 characters only?
Some users have more than that, this is my code:
$cryptedpassword='{crypt}74boAULE9gF5.';
if( preg_match( "/{([^}]+)}(.*)/", $cryptedpassword, $cypher ) ) {
$cryptedpassword = $cypher[2];
$_cypher = strtolower($cypher[1]);
} else {
$_cypher = NULL;
}
if( preg_match("/^\\$2+/",$cryptedpassword ) ) {
// make sure that web server supports blowfish crypt
if( ! defined( 'CRYPT_BLOWFISH' ) || CRYPT_BLOWFISH == 0 )
pla_error( _('Your system crypt library does not
support blowfish encryption.') );
list(,$version,$rounds,$salt_hash) =
explode('$',$cryptedpassword);
if( crypt( $plainpassword, '$'. $version . '$' .
$rounds . '$' .$salt_hash ) == $cryptedpassword )
return true;
else
return false;
}
elseif( strstr( $cryptedpassword, '$1$' ) ) {
if( ! defined( 'CRYPT_MD5' ) || CRYPT_MD5 == 0 )
pla_error( _('Your system crypt library does not
support md5crypt encryption.') );
list(,$type,$salt,$hash) = explode('$',$cryptedpassword);
if( crypt( $plainpassword, '$1$' .$salt ) == $cryptedpassword )
return true;
else
return false;
}
elseif (strstr( $cryptedpassword, '_' ) ) {
if ( ! defined( 'CRYPT_EXT_DES' ) || CRYPT_EXT_DES == 0 )
pla_error( _('Your system crypt library does not
support extended DES encryption.') );
echo crypt($plainpassword, $cryptedpassword );
if( crypt($plainpassword, $cryptedpassword ) ==
$cryptedpassword )
return true;
else
return false;
}
else {
if( crypt($plainpassword $cryptedpassword ) == $cryptedpassword)
return true;
else
return false;
}
The issue is the 8 character limitation, even If i have a password
of 10 characters, the function will just take 8, how can I deal with
this issue?
Thanks for your time my firiends!!!
