(ITS#8167) The new non-blocking TLS connect does not work in a reference/referral
by ipuleston＠sonicwall.com 08 Jun '15

08 Jun '15

Full_Name: Ian Puleston Version: 2.4.40 OS: VxWorks URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (204.118.31.3) I've been using the new non-blocking TLS connect feature added in version 2.4.34 (issue #7428, compiled with LDAP_USE_NON_BLOCKING_TLS) and found a problem that it does not work in a reference/referral. It only works on the default connection, and that can cause a long or permanent hang in SSL_connect as follows, even when a network timeout is set and LDAP_USE_NON_BLOCKING_TLS is on: ldap_result -> ldap_chase_v3referrals ldap_chase_v3referrals -> ldap_send_server_request ldap_send_server_request -> ldap_new_connection ldap_new_connection -> ldap_int_open_connection ldap_int_open_connection -> ldap_int_tls_start ldap_int_tls_start -> ldap_pvt_tls_connect ldap_pvt_tls_connect -> (v0) tlso_session_connect -> SSL_connect The problem is that the calls to ber_sockbuf_ctrl with LBER_SB_OPT_SET_NONBLOCK pass the Sockbuf as ld->ld_sb where they should be passing it as sb, that being the Sockbuf for this connection. The following 3 changes in ldap_int_tls_start fix it: Change: ber_sockbuf_ctrl( ld->ld_sb, LBER_SB_OPT_SET_NONBLOCK, sb ); to: ber_sockbuf_ctrl( sb, LBER_SB_OPT_SET_NONBLOCK, (void*)1 ); Change: ber_sockbuf_ctrl( ld->ld_sb, LBER_SB_OPT_SET_NONBLOCK, sb ); to: ber_sockbuf_ctrl( sb, LBER_SB_OPT_SET_NONBLOCK, (void*)1 ); Change: ber_sockbuf_ctrl( ld->ld_sb, LBER_SB_OPT_SET_NONBLOCK, NULL ); to: ber_sockbuf_ctrl( sb, LBER_SB_OPT_SET_NONBLOCK, NULL )B3B Note I also changed the 3rd argument there from "sb" to "(void*)1" just because I think passing sb there is a little confusing. Either will work fine. Ian

(ITS#8166) translucent overlay - compatibility with other overlays that need write access
by thomcz＠gmail.com 08 Jun '15

08 Jun '15

Full_Name: Thomas Keil Version: 2.4.40 OS: Debian 8.0 Jessie URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (139.30.84.202) This is a software enhancement request. I have the following use case at hand: My university provides a central LDAP directory which authenticates users but does not contain group information. For my institute we want to set up our own OpenLDAP server which relays the user authentication to the central directory (via back_ldap) but additionally provides group information. This should be used by a network of linux machines for user authentication, group management and login filtering. For reasons of high availability we want to replicate our local LDAP server using the builtin replication mechanism of OpenLDAP. This seems to be a nice example for the use of the translucent backend. Nevertheless group membership (for login filtering) can only be provided using the memberof overlay which (so it seems) is not compatible with the translucent overlay. Furthermore the syncprov overlay needs to access the lastmod attribute which is disabled for databases using the translucent overlay. Thus a local database combined with the translucent overlay cannot be replicated at all. To me it seems that these problems can be solved by allowing write access to the local database for other overlays when used in combination with the translucent overlay. It would make this overlay much more useful than it is right now since it would allow to use this in large scale deployments as well (where replication is essential). This is valid especially for cases where the local administration has no write access to the central directory.

(ITS#8165) Add proper versioning to liblmdb
by quanah＠openldap.org 05 Jun '15

Full_Name: Quanah Gibson-Mount Version: HEAD OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.111.52.177) LMDB has matured to the point at which it should be creating a properly versioned library for linking. Currently, only liblmdb.so is created. It would be preferable to see it in libtool format (liblmdb.so.x.y.z). Should be done for the 0.9.15 release.

I think this would violate the purpose and specification of matchedDN. It would be more appropriate to have that piece of info returned within the control value of a specifically designed response control, when the control is explicitly requested. What you're asking for could perhaps be logged, if it isn't yet. My 2c.

Full_Name: Michael Str.der Version: HEAD OS: URL: Submission from: (NULL) (212.227.35.94) It would be handy if slapo-unique could set matchedDN along with result code constraintViolation(19) to a DN of an existing entry causing the constraint to fail. To avoid information disclosure ACL checking could be performed to determine whether the bound identity has at least search privilege on the entry pseudo attr and unique attr.

Yes, then it should be sockaddr_storage. sockaddr breaks for any address type which is bigger than sizeof(struct sockaddr), which can be small. sockaddr_storage only breaks on an OS which complains when it is too big for the specified address type. -- Hallvard
