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; sub procentry { my ( $mesg, $entry) = @_; # Return if there is no entry to process if ( !defined($entry) ) { return; } print "dn: " . $entry->dn() .

Certificate authentication and back-ldap proxy
by Ubay Dorta Guerra 27 Dec '10

Hi, We have some problems with certificate authentication when the master server is behind a back-ldap proxy. We have openldap 2.4.21 on Suse Linux Enterprise Server 10 SP3 and these are the details of our scenario: The master server: server1.example.com has the following slapd.conf file: access to dn.base="" by * read access to dn.base="cn=Subschema" by * read access to attrs=userPassword,userPKCS12 by self write by dn.exact="CN=admin_w_cert,O=Internet Widgits Pty Ltd,ST=Some-State,C=AU" read by * auth access to attrs=shadowLastChange by self write by * read access to * by * read # # Security SSL # TLSCipherSuite HIGH:MEDIUM:+SSLv3 TLSCertificateFile /etc/ssl/certs/server1.example.com.pem TLSCertificateKeyFile /etc/ssl/private/server1.example.com.key TLSCACertificatePath /etc/ssl/cacerts/ TLSVerifyClient demand # #Log level # loglevel 256 # Require authentication require authc ####################################################################### # HDB database definitions ####################################################################### database hdb suffix "dc=example,dc=com" checkpoint 1024 5 cachesize 10000 rootdn "cn=Manager,dc=example,dc=com" rootpw secret # Indices to maintain index objectClass eq # Overlay ppolicy overlay ppolicy ---------------------- Authentication is required, and we give access to the user passwords for the dn of a certificate.

comp match module has unusable X509 cert code
by Lehnert, Hartmut 10 Aug '10

10 Aug '10

Hi all! I have performed some tests with the comp match module (yes it runs if you work around ITS 6556 ;-)). The result is that the comp match module only works with very simple X509 certs that use old algorithms! For example if you use X509 certificates with long serial numbers the snacc generated asn.1 parser (contained in file certificate.c) fails decoding the serial number. Another drawback: The attributes in Name components subject and issuer (cn, c, o, ou) have to be PrintableStrings; if for example there is an UTF8String present in the issuer the asn.1 parser fails decoding the issuer. All modern algorithms (sha256WithRSA, sha512WithRSA) are not recognized by the parser; if your X509 certificate is signed with sha256WithRSA the asn.1 parser fails decoding the AlgorithmIdentifier. In modern times these drawbacks aren't acceptable. Another appropriate asn.1 module for the X509 certificate structure has to be compiled with the openldap esnacc compiler. I would have done this but the openldap esnacc fails parsing its own modules!!! See something like this: openldap@ocsp-openldap24:~/Certificate> ~/openldap-snacc-2.3.6/compiler/esnacc -E BER_COMP -E GSER -t -d -f -I /home/openldap/openldap-snacc-2.3.6/asn1specs -I . Certificate.asn1 /home/openldap/openldap-snacc-2.3.6/asn1specs/asn1module.asn1(91) : parse error at symbol ""OID"" Parsing errors---cannot proceed The code in the asn.1 module: 88 ModuleId ::= SEQUENCE 89 { 90 name MyString, 91 oid OBJECT IDENTIFIER OPTIONAL --snacc cTypeName:"OID" isPtr:"TRUE" 92 } 93 Does anybody know how the esnacc error can be avoided? Regards, Hartmut

OpenLDAP, PADL and querying multiple ADs
by Markus 07 Jul '10

07 Jul '10

Hello list, I'm on SLES 11 and the mission is to allow Active Directory (AD) users to log in to Linux. The difficulty is that those users are stored in two separate ADs which have no connection to each other. Both ADs are running on Windows 2003 R2 (or later) and I'm using the LDAP PADL NSS (/etc/ldap.conf) implementation to map the UNIX attributes that are stored in the AD to local values (homedir, shell, UID/GID etc.). So far so good, everything works fine (getent passwd, PAM logins). Now, when searching for a solution on how to query two ADs via LDAP at the same time it seems like OpenLDAP supports multiple LDAP search bases, and there was also a mentioning of the translucent overlay feature, so I suppose using OpenLDAP I could fetch the UNIX attributes from both ADs simultaneously. What completely puzzles me is the NSS/PAM configuration and how PADL NSS and OpenLDAP interact respectively not interact: - If I configure OpenLDAP (/etc/openldap/ldap.conf) instead of PADL NSS (/etc/ldap.conf) how do I configure NSS/PAM for OpenLDAP? I need "getent passwd" and "getent group" and of course PAM logins to work. E.g. getent passwd has to give me back all users from BOTH ADs that have UNIX attributes stored. But since there seems to be only the PADL NSS module in existance (/lib/libnss_ldap.so.2), I am clueless on how to integrate the OpenLDAP variant. Shouldn't there be something like /lib/libnss_openldap.so and shouldn't I be able to add something like "passwd: compat openldap" to /etc/nsswitch.conf? I guess not, but I don't understand why. - So that leaves me with the idea of *somehow* fetching the UNIX attributes from both ADs via OpenLDAP, set up a local OpenLDAP server to store this information in, and then using the PADL NSS module to query it. I'm not sure if this is the right approach or if this is even technically feasible. Is there maybe a easier way with less overhead (e.g. no OpenLDAP server required). Thank you very much for any hints or pointers that you might share with me! I'm really lost... Best regards Markus

meta setup
by Gidobo 69 05 Jul '10

05 Jul '10

Hi, I plan to set up a meta directory. It looks like a normal one according to the openldap descriptions so I was surprised that I was unable to find any howto/faq/forum entry/mailing about it. Let me describe it: I have a heterogeneous system and want to have a common ldap system for it. Here is what I have now: Two AD domains An openldap db for a software with internal users. My aim: - To be able to authenticate a domain user from either AD. - To have non-AD users as well. - To have non-AD attributes for all three. So for authentication: If user is an AD user -> authenticate from appropriate DC If user is a non-AD one -> authenticate from openldap If I want non-AD attribute added to AD users as well. If an attribute doesn't exist for an AD user in openldap ask the appropriate DC. This way I could user AD users and their groups through openldap, have independent non-AD users and have attributes for all users in openldap local db regardless of authentication source. Have I missed something and this is too 'exotic'? Example: ad1.company.com -> AD1 users, authenticates from DC1 ad2.company.com -> AD2 users, authenticates from DC2 ldap.company.com -> 'other' users, authenticates from openldap local db Attributes mapped. If user is an AD one and attribute doesn't exists in local DB, proxy the query to AD. Thanks in advance Gidobo

ACL to allow an attribute to be cleared, but not changed to something else?
by Tim Gustafson 01 Jul '10

01 Jul '10

Hi, I'd like to let my account managers to clear the passwords of their managees in the event that an employee is no longer active. So, I've got an ACL like this: access to attrs=userPassword,sambaNTPassword by set="this/manager & user" write by * break But I realized that the ACL also allows the manager to -change- a user's password, which I don't really want. Is there some ACL that I can grant that would let a manager remove an attribute from another user's account, but not otherwise change the value of that attribute?

Adding Schema
by Alexander Erameh 01 Jul '10

01 Jul '10

Hi, Just joined this list, so please pardon me for any mistakes. I have been trying to add "CourierMailAccount" object class and "qmailUser" object class for days without success. I created a schema file and defined the Attributetypes and Object classes and added the file in the Include statement in slapd.conf but SLAPD does not seem to recognize the new object classes. When I try to add users to the Database using LDAPADD, I get the error message below: "ldap_add: Invalid syntax (21) additional info: objectClass:value #2 invalid per syntax" The #2 objectClass is "qmailuser". Suggestions and advice will be appreciated. Alexander <file:///C:\Program%20Files\Common%20Files\Microsoft%20Shared\Stationery\fie ruled.gif>

Did I miss anything? Please note that I'm trying to use the same kerberos principal as my user, and this is intended. I did try adding another user (account and posixAccount objectClasses) with a separate kerberos principal and that did not work either. Lastly, here is my slapd.conf: include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/inetorgperson.schema include /etc/ldap/schema/kerberos.schema pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel none modulepath /usr/lib/ldap moduleload back_hdb sizelimit 500 tool-threads 1 backend hdb database hdb suffix "dc=domain,dc=com,dc=br" rootdn "cn=admin,dc=domain,dc=com,dc=br" directory "/var/lib/ldap" dbconfig set_cachesize 0 2097152 0 dbconfig set_lk_max_objects 1500 dbconfig set_lk_max_locks 1500 dbconfig set_lk_max_lockers 1500 index objectClass eq lastmod on checkpoint 512 30 access to attrs=userPassword,shadowLastChange,krbPrincipalKey,krbLastPwdChange by dn="cn=admin,dc=domain,dc=com,dc=br" write by anonymous auth by self write by * none access to dn.base="" by * read access to * by dn="cn=admin,dc=domain,dc=com,dc=br" write by * read Thanks for the help! -- Diego Lima
