First question...

Hi! I am Daniel from argentina, I have an strange problem that, after been looking for it, I am really lost. I have made an objectClass in open ldap 2.4.7-6.1 and it works perfectly, but when I implemented in an open ldap 2.3.27-1. it did't work. It fails with the message, ldap_add: Invalid syntax (21) additional info: objectClass: value #0 invalid per syntax. Are there any main difference in schema 's structure between those ldap versions? Where could be the problem? attributetype ( 1.3.6.1.4.1.4203.666.1.124 NAME 'dynastyName' DESC ' Nombre dynasty.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) attributetype ( 1.3.6.1.4.1.4203.666.1.125 NAME 'vars' DESC ' Valores obtenidos de dynasty.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) objectclass (1.3.6.1.4.1.4203.666.1.54775 NAME 'jxfsDevice' SUP top STRUCTURAL DESC 'Estructura de un dispositivo jxfs' MAY ( cn $ vars $ dynastyName)) Thanks in advance! -- Daniel Padula.

error while accessing through Java "javax.naming.AuthenticationNotSupportedException: simple"
by Sai 07 Apr '08

07 Apr '08

Hi I am new to openLDAP. I am configuring it (version: OpenLDAP: slapd 2.3.27) on a Linux machine to use with our Web Application (java). When I try and make a connection I am getting the following error. =============== javax.naming.AuthenticationNotSupportedException: simple [4/7/08 10:42:01:887 EDT] 00000026 SystemErr R at com.sun.jndi.ldap.sasl.LdapSasl.saslBind(LdapSasl.java:115) =============== These are the code / attributes I used. ================= Hashtable env = new Hashtable(); env.put( Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory" ); env.put( Context.PROVIDER_URL, "ldap://<machine name>:<port>" ); env.put( Context.SECURITY_PRINCIPAL, "cn=uimadmin,ou=UIM,o=nhes,dc=nh,dc=gov" ); env.put( Context.SECURITY_AUTHENTICATION, "simple" ); env.put( Context.SECURITY_CREDENTIALS, "<password in plaintext>" ); try { context = new InitialDirContext(env); System.out.println("CONTEXT OPENED WITH ADMIN ACCOUNT"); } catch (NamingException ne) { ne.printStackTrace(); LogManager.logMessage("LDAPManager.getAdminJndiContext()", ne); } return context; ================= When I try and do an ldapsearch with a -x option (simple authentication) on the command line, it is returning results successfully. I am also able to connect using ldapbrowser v2.8.2 and see the results. Any help regarding this is greatly appreciated. Thanks in advance. -Bangaru.

Questions about Active Directory Password Cache overlay
by Wes Modes 07 Apr '08

07 Apr '08

Thanks to Buchan Milne, I'm looking into the Active Directory Password Cache overlay for OpenLDAP, which seems to offer more or less what I'm trying to do. Is anyone here experienced with it? Is this the right place to ask or is there an openLDAP overlays list? I understand this description of ADPC: Active Directory Password Cache =============================== Active Directory does not provide any means to read user credentials on any public API. It is possible, to install additional libraries as password sniffer to catch and forward cleartext passwords on changes. In case you cannot or simply dont want to install such libraries, the Active Directory Password Cache overlay is your option. The Active Directory Password Cache overlay allows to mirror user account credentials without any modification on the AD server. It only takes one occasional simple bind authentication against the OpenLDAP server. If the credential has not been mirrored yet, the overlay uses the krbPrincipalName and the password provided by the user to perform a Kerberos init against the Active Directory. A successful Kerberos init guarantees a correct password for this principal, and therefor the bind finally succeeds. Within this overlay operation, the password gets encrypted with the default OpenLDAP hash alorithm and stored as userPassword attribute. There is an option to update the sambaNTPassword also (using code borrowed from Howard Chu's smbk5pwd overlay). All following simple bind authentications will first try these cached credentials, making the OpenLDAP server independent from AD. In case the user changes its password on the Active Directory server, the old password stays valid in OpenLDAP until the user first presents the new password for an simple bind. Within this bind operation, the overlay performs another Kerberos init and updates the cached credentials in OpenLDAP. It is clear to me that after a password change, that a failure to authenticate initiates a new auth attempt against the KDC, and if it succeeds, ADPC caches the passwd as a hash in OpenLDAP. But if Samba fails to authenticate against the hash stored in sambaNTPassword, is a new authentication attempt made against the KDC? And if it does, where does it get the passwd to hash (since Samba never gets the passwd in NTLM authentication)? Practically speaking, it seems that the password that the overlay hashes has to come from a source other than Samba. A web app? How have people used it in the past?

openLDAP controls‏
by Gene Kupfer 05 Apr '08

05 Apr '08

Hello, I’m trying to figure out how to enable some controls, but can’t find a single thing online that references this topic. The controls are defined in the ldap.h file (please see below), but when I query my directory for supported controls it does not show them in the list. #define LDAP_CONTROL_SORTREQUEST "1.2.840.113556.1.4.473" #define LDAP_CONTROL_SORTRESPONSE "1.2.840.113556.1.4.474" #define LDAP_CONTROL_VLVREQUEST "2.16.840.1.113730.3.4.9" #define LDAP_CONTROL_VLVRESPONSE "2.16.840.1.113730.3.4.10" I’m trying to connect an application that lists these controls as CRITICAL and fails to show the LDAP users and groups. Thank you very much for your help. Gene

Samba authentication to Kerberos via OpenLDAP, third and last try
by Wes Modes 04 Apr '08

04 Apr '08

So far answers I've received about this have been inconsistent at best and downright inaccurate at worst. I'm going to try one more time and see if, at the very least, someone can give me a lead. I ask you to consider what I'm asking remotely possible, and then seek a solution. (Particularly before one blasts off an ill-thought out message that says simple, "Can't be done," simple because you've never done it or haven't heard of it being done.) So consider this a challenge or a riddle. 1. I have an OpenLDAP directory server that I am using for user and group information. I would like to use it also to authenticate against. This way, whatever I hook up to it (Samba, webstuff, PHP apps, CMS) can both authenticate and authorize from one source. 2. There is a separate Kerberos server that has users' campus-wide passwords. I have access to it, but do not control it. 3. I have a separate linux file server running Samba. PCs and Macs will connect to it. I know I can do Kerberos authentication directly from Samba, but I'd prefer OpenLDAP do the Kerberos connection. Here's why: a) I can solve the problem once, rather than have to work out BOTH LDAP and Kerberos connections for every new authenticated service I add, and b) LDAP hooks are more common than Kerberos hooks for other services for which I will eventually want authentication and authroization. And yes, I know it breaks the Kerberos model. The question and the challenge: Any leads on how I might convince Samba to pass the input password on to OpenLDAP so that OpenLDAP can authenticate it against Kerberos?

Migration to 2.4.8 version
by uri_gr1＠tut.by 04 Apr '08

04 Apr '08

Hi, people! I'm atemptting to migrate to openldap-2.4.8(I realy need mirrormode replication). But some problems appear, first of all, number of ldap editors(gq, luma, JXplorer) can't add new entries into ldap tree, actually only phpldapadmin can do than; second, can't setup pam_ldap/nss_ldap to authenticate via openldap-2.4.8. Last one really makes new openldap version completely unusable. Is any way to solve this problems?
