(ITS#5919) URI syntaxe (ldap:///dc=my%2cdc=domaine)
by Philippe.eychart＠informatique.gov.pf 03 Feb '09

Full_Name: Philippe EYCHART Version: 2.4.13 OS: slack12 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (123.50.82.141) Hi, The "tool_conn_setup" function (in common.c) autorise the Url synthaxe "ldap:///dc=my%2cdc=domaine" which produce a SRV request to find the best server to request (not yet according the rfc 2782 - I've made dnssrv.c patch to implement priorities and I try to implement weight before submit this work). So, the client tools - ldapsearch, ldapadd, ... permit this syntaxe (via "ldap_dn2domain" and "ldap_domain2hostlist" functions). Unfortunately, ldap_initialize() doesn't use these functions (but only ldap_url_parselist_ext()) and doesn't allow this synthaxe. So, other packages (like SAMBA) doesn't enjoy this capability : "passdb backend = ldapsam:ldap:///dc=my%2cdc=domain" according a SRV definition "_ldap._tcp.my.domain. IN SRV ..." Is there any reason for that ? Can we envisage to increase this possibility ? Regards

(ITS#5918) slapacl(8c) badly worded
by quanah＠zimbra.com 03 Feb '09

Full_Name: Quanah Gibson-Mount Version: RE24 OS: NA URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.111.29.239) Slapacl is used to check the behavior of the slapd in verifying access to data according to ACLs, as specified in slapd.access(5). It opens the slapd.conf(5) configuration file, reads in the access directives, and then parses the attr list given on the command-line; if none is given, access to the entry pseudo-attribute is tested. Besides the bit about "of the slapd", the first sentence is rather awkward.

(ITS#5917) slapd crashes with assertion failed and SIGABRT
by guido＠keamera.org 02 Feb '09

02 Feb '09

Full_Name: Guido Landi Version: 2.3.43 OS: linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (194.246.126.62) Hello, I'm using OpenLDAP 2.3.43 with ldap backend as a proxy to Active Directory for users autentication on linux(gentoo). OpenLDAP keep on crashing while testing it through the nss_ldap module using the "id" unix command. It often crashes for an assertion failed(that i can easily reproduce) but sometimes with a segmentation fault or a glibc error related to free()(heap corruption?). I found as a workaround that if I set the maximum threads number to 2 it works just fine. I'm using glibc-2.6.1 with NPTL and I have compiled OpenLDAP with gcc-4.1.2 and 3.4.6. Here is my slapd.conf, ldap.conf(used by the nss_ldap module) and some backtraces. #### slapd.conf #### pidfile /var/run/openldap/slapd.pid argsfile /var/run/openldap/slapd.args include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/local.schema modulepath /usr/lib/openldap/openldap moduleload rwm overlay rwm rwm-map attribute cn sAMAccountName database ldap suffix "dc=mydomain,dc=it" rootdn "ou=CV Utenti,dc=mydomain,dc=it" lastmod off uri ldaps://mydc.mydomain.it/ rebind-as-user chase-referrals YES index objectClass eq,sub index uidNumber,gidNumber eq index memberUid eq index sAMAccountName eq,subinitial #concurrency 0 #threads 2 TLSCACertificateFile /etc/openldap/ssl/cacert.pem TLSCertificateFile /etc/openldap/ssl/server.pem TLSCertificateKeyFile /etc/openldap/ssl/server.key TLSCipherSuite ALL TLSCRLCheck none TLSReqCert none TLSVerifyClient never #### ldap.conf #### uri ldaps://ldap-proxy.mydomain.it port 636 base OU=mygroup,dc=mydomain,dc=it scope sub binddn CN=myaccount,DC=mydomain,DC=it bindpw password bind_policy soft ldap_version 3 #nss_schema rfc2307bis #debug 1000 REFERRALS no pam_login_attribute cn pam_filter objectClass=user pam_password ad pam_groupdn CN=UNIX Admins,DC=mydomain,DC=it #pam_groupdn CN=UNIX-USERS,DC=mydomain,DC=it pam_member_attribute member nss_base_passwd OU=Users,DC=mydomain,DC=it nss_base_shadow OU=Users,DC=mydomain,DC=it nss_base_group DC=mydomain,DC=it?(objectClass=group) nss_map_objectclass posixAccount user nss_map_objectclass shadowAccount user nss_map_attribute uid uid nss_map_attribute uniqueMember member #nss_map_attribute uniqueMember msSFU30PosixMemberOf nss_map_attribute userPassword unixUserPassword nss_map_attribute homeDirectory unixHomeDirectory nss_map_attribute loginShell loginShell nss_map_attribute gecos name nss_map_objectclass posixGroup group nss_reconnect_tries 4 nss_reconnect_sleeptime 1 #nss_reconnect_maxsleeptime 16 nss_reconnect_maxconntries 6 #nss_initgroups backlink #nss_max_group_depth 100 ssl yes #### backtraces #### put_simple_filter: "member=cn=certsvc_dcom_access,cn=users,dc=mydomain,dc=it" ldap_send_initial_request ldap_send_server_request ldap_back_retry: conn 0x826a628 refcnt=2 unable to retry. slapd: bind.c:157: ldap_back_conn_delete: Assertion `!(*(&((lc))->lc_lcflags) & (((0x00000020U))))' failed.

Well, that's ldap_int_search*(); let's vote for the "public" name. As I said, I think it makes sense, since alias dereferencing has always been explicitly required in the request. OTOH, I have no objection to using a client-side control, as it wouldn't add too much complexity (well, it'd require to parse a list of strings with a worst-case of N * M, with N: number of known client controls; M: client controls passed to the request), and it would pave the way for client controls in libldap :) I see Hallvard already has a request for another one. One consideration: I'm not overlooking the value of not changing the API too often; also, I fear client-side controls could be another way to wind up with revitalizing the old API instead of designing a new one - if anyone ever seriously considered the opportunity to design it. p.

Yes, the missing aliases argument is an API design bug. The API almost but not quite has functions that match the protocol messages. If we are going to export yet another search function, I'd like to see another feature added as well: A way to pass the BER form of a filter to the search function. And some helpers to build the BER form, and to parse it back into the string form of a filter. Filters are complex enough that it can be a pain to deal with the string form and its quoting at times. Of course, that one could be a client control too - e.g. combined with passing NULL as the filter... -- Hallvard

Hmm, maybe I missed something in this discussion and about the usage of client controls. But I'd vote for another function which provides a complete set of arguments for sending search requests. So if ldap_search_ext is considered incomplete regarding alias dereferencing I'd vote for introducing ldap_search_ext2 (or whatever name) with an additional argument. Ciao, Michael.
