Support for ordering matching rules in extensible match filters?
by Daniel 22 Apr '10

22 Apr '10

Hi, why doesn't slapd support ordering matching rules in extensible match filters? Does the small code enhancement for slapd's generalizedTimeOrderingMatch() would make sense into the direction to support ordering matching in extensible filters (in this particular case)? Thanks a lot! Cheers Daniel static int generalizedTimeOrderingMatch( int *matchp, slap_mask_t flags, Syntax *syntax, MatchingRule *mr, struct berval *value, void *assertedValue ) { struct berval *asserted = (struct berval *) assertedValue; ber_len_t v_len = value->bv_len; ber_len_t av_len = asserted->bv_len; /* ignore trailing 'Z' when comparing */ int match = memcmp( value->bv_val, asserted->bv_val, (v_len < av_len ? v_len : av_len) - 1 ); Debug( LDAP_DEBUG_TRACE, "gTOM1: %s %s %d\n", value->bv_val, asserted->bv_val, match); if ( flags & SLAP_MR_EXT ) { Debug( LDAP_DEBUG_TRACE, "gTOM: MR => SLAP_MR_EXT (%ld) [%d %d]\n", flags, 0, 0); if ( match == -1 ) match = 0; else if ( match == 0 ) match = 1; } else { Debug( LDAP_DEBUG_TRACE, "gTOM: MR => ? (%ld) [%d %d]\n", flags, 0, 0); if ( match == 0 ) match = v_len - av_len; } Debug( LDAP_DEBUG_TRACE, "gTOM2: %s %s %d\n", value->bv_val, asserted->bv_val, match); *matchp = match; return LDAP_SUCCESS; }

Help with objectClass and attribute definition.
by Techie 22 Apr '10

22 Apr '10

Hello, I am looking to add attributes containing server names to my ldap accounts. Does anyone know of an existing LDAP objectClass that will allow multiple attribute definitions that can be used for server names. For example.. objectClass: Servers sharebox: homeserver.example.com sharebox: dataserver.example.com I would really like to avoid creating my own objectClass and attribute definitions as I am sure some already exist. Thank you

Good Morning All, I need to capture the following stats for a serving LDAP. total_connections bytes_sent completed_operations initiated_operations referrals_sent entries_sent bind_operations unbind_operations add_operations delete_operations modify_operations compare_operations search_operations write_waiters read_waiters I have switched on the monitor mode on LDAP but not sure how can I get these statistics from that.

OpenLDAP and SSH authentification
by Michel Dubois 21 Apr '10

21 Apr '10

Hello Everyone, I'm newbie on OpenLDAP. I build a LDAP server with one user. I can see this user when I did a "getent passwd" on my client. This is meaning that my LDAP server is working and my client is connecting on the LDAP server. I already modify my */etc/pam.d/sshd file on t my client machine like this : * * # auth auth required pam_nologin.so no_warn auth sufficient pam_opie.so no_warn no_fake_prompts auth requisite pam_opieaccess.so no_warn allow_local auth sufficient /usr/local/lib/pam_ldap.so no_warn auth required pam_unix.so no_warn try_first_pass # account account required pam_login_access.so account required pam_unix.so # session session required pam_permit.so # password password required pam_unix.so no_warn try_first_pass * But I can't be connected in shh mode on my client machine with the user login ? And this modification disable my ssh root connection. What do I have to check? Regards, -- ----------------------------------------------------------- Michel Dubois

Which would be true, our LDAP tree has no cn=config. We get the same error on the primary server, so I suppose it is ApacheDS trying to look for what would be in the Apache LDAP implementation. But that's the only error I can find, everything else is miles and miles of "search access granted". I tried to get it to list DN="dc=domain,dc=com" by hand from ApacheDS, and it would not return anything (it says "No base DN returned from server.") although in the logs it shows: conn=6 op=3 SRCH base="dc=domain,dc=com" scope=0 deref=3 filter="(objectClass=*)" conn=6 op=3 SRCH attr=hasSubordinates objectClass => hdb_search bdb_dn2entry("dc=domain,dc=com") => access_allowed: search access to "dc=domain,dc=com" "entry" requested <= root access granted access_allowed: search access granted by manage(=mwrscxd) base_candidates: base: "dc=domains,dc=com" (0x00000001) send_ldap_result: conn=6 op=3 p=3 send_ldap_result: err=0 matched="" text="" send_ldap_response: msgid=4 tag=101 err=0 But when I run the ldapsearch command (as any user) from other computers on the network it returns the DN's information... So I am thoroughly confused... I am pretty sure it is not logging in as anonymous, but I have no idea why only the ldapsearch command is the only thing that can authenticate and retrieve information. It is the same version of openldap as the primary server, it has the same exact config, it has all the same schema loaded, it has the exact full ldap tree. I'm going to explode!@$#@ -a

Outlook and Thunderbird Browsing Openldap
by Kalpin Erlangga Silaen 21 Apr '10

21 Apr '10

Hello all, I have install openldap on CentOS 5.4 (via yum). I want use this openldap for shared address book. I tested on thunderbird and outlook 2007 with results below: on thunderbird: 1. Compose new email, while I type some letter in field To: ; thunderbird can lookup into openldap content 2. In Addressbook menu, I can lookup the content after put some letter in search field and click search 3. in addressbook menu, while I click openldap addressbook, thunderbird can not browse or display all contents (my openldap content only 3 address book for test) basicly I do not have problem with thunderbird integration openldap on outlook 2007 1. Compose new email, while I type some letter in field To: ; outlook can not lookup into openldap content 2. In Addressbook menu, I can lookup the content after put some letter in search filend and click search. 3. In address book menu, while I click Openldap addressbook, outlook 2007 can not browse or display all contents (my openldap content only 3 address book for test). Is it possible to make outlook 2007 for below missions: 1. While compose new email, if I type some letter in field To: ; outlook 2007 supposed to lookup to openldap 2. In addressbook menu, if I click Openldap addressbook, suppose outlook 2007 display all content (limited in configuration) Any idea?
