loading slapo-vc does not work
by Michael Ströder 01 May '21

01 May '21

HI! Trying to understand Verify Credentials operation I'd like to initialize slapo-vc but it fails (see simple config below). 608d43ae.18d5fdad 0x7f6e38b66740 slapd.conf: line 13 (overlay vc) 608d43ae.18d623b1 0x7f6e38b66740 overlay "vc" not found 608d43ae.18d6dd5c 0x7f6e38b66740 slapd.conf: line 13: <overlay> handler exited with 1! Also tried to load it in global section but this also does not work. The following files are installed (and other overlays from this directory load just fine): # ls -al /opt/openldap-ms/lib64/openldap/vc* -rw-r--r-- 1 root root 1008 May 1 02:40 /opt/openldap-ms/lib64/openldap/vc.la lrwxrwxrwx 1 root root 11 May 1 02:40 /opt/openldap-ms/lib64/openldap/vc.so -> vc.so.0.0.0 lrwxrwxrwx 1 root root 11 May 1 02:40 /opt/openldap-ms/lib64/openldap/vc.so.0 -> vc.so.0.0.0 -rwxr-xr-x 1 root root 18824 May 1 02:40 /opt/openldap-ms/lib64/openldap/vc.so.0.0.0 Find build config herein: https://build.opensuse.org/package/view_file/home:stroeder:openldap25/openl… What's wrong here?

Spec for LDAP Verify Credentials operation
by Michael Ströder 30 Apr '21

30 Apr '21

HI! Is there a spec for client-side implementation of LDAP Verify Credentials operation? I assume that one has to grant auth access to 'userPassword' to the entity sending the VC operation. Ciao, Michael.

multival member ...
by Michael Ströder 30 Apr '21

30 Apr '21

HI! Experimenting with 2.5.4 I wonder what are reasonable values for applying multival to attribute 'member' in group entries. I guess this depends on length of member DN values. Is there a clear way to calculate this? Or how to find out the effect of current settings. Ciao, Michael. P.S.: Yes, I know I have to reload the database when adding multival config option.

Groups and accesses
by Клеусов Владимир Сергеевич 27 Apr '21

27 Apr '21

Hi, there was an idea to use OpenLDAP as an address book for mail. Tell me the idea of how to make it so that there are two groups. The members of one see all of them (i.e. the general address book) and only the admin edits them. The members of the other are only seen and edited by the owner (i.e. the personal address book)

Unable to delete root entry
by Николай Данилов 26 Apr '21

26 Apr '21

When installing openldap with database mdb, root entry cannot be deleted. Tested on systems: OS Linux Debian 10, slapd 2.4.57+dfsg-2 Arch Linux, openldap 2.4.58-1 Oracle Linux 8, openldap 2.4.58 (from source) The root entry was created by the command: ldapadd -x -D 'cn=admin,dc=example,dc=org' -f root_entry.ldif Content of the root_entry.ldif file: dn: dc=example,dc=org objectClass: dcObject objectClass: organization dc: example o: Example description: Example directory dn: cn=root,dc=example,dc=org objectClass: organizationalRole cn: root description: Directory Manager Trying to delete the root entry: ldapdelete -x -r 'dc=example,dc=org' -D 'cn=admin,dc=example,dc=org' -w admin Output - ldap_delete: No such object (32) How can I delete the root entry and create a new one with other structural objectclasses?

OpenLDAP 2.5 Release Candidate Testing (OpenLDAP 2.5.4)
by Quanah Gibson-Mount 24 Apr '21

24 Apr '21

This is a testing call for OpenLDAP 2.5 Release Candidate (OpenLDAP 2.5.4) Depending on the results, this may be the only testing call. Generally, get the code for RE25: <https://git.openldap.org/openldap/openldap/-/archive/OPENLDAP_REL_ENG_2_5/o…> Extract, configure, and build. Execute the test suite (via make test) after it is built. Optionally, cd tests && make its to run through the regression suite. Note that there are new features in 2.5, so please examine the options available with configure carefully. Some examples: The new load balancer, which can either be built as a module for slapd (--enable-balancer=mod) or as a standalone server (--enable-balancer=yes) The libargon2 password module (--enable-argon2). Systemd notification support (--with-systemd=yes). Thanks!

Best way to secure LDAP to public Server
by work＠seyboldt.org 19 Apr '21

19 Apr '21

Hey, i need to open my LDAP-Directory to a public available Server. What is the best secure way to connect my LDAP-Server to my Public server? I thought about a proxy to my Firewall there I could specify requests to my LDAP-Server, or is there a better or an official way to do this? Thanks, RMs3Q

Config files & env vars not read when geteuid() != getuid()
by Norm Green 18 Apr '21

18 Apr '21

Hello LDAP users and maintainers, libraries/libldap/init.c has this code which bypasses read all LDAP config env vars when the exe loadlig libldap is running in setuid mode. This is causing problems for one of our customers who routinely run our product Linux executables (which load our libldap) in setuid mode for legitimate purposes. Since we have the source, we can and may change this code. In our case, customer wants to set env var LDAPCONF to point at a non-default conf file but is unable to do so. In fact this code bypasses almost all ways an alternate config file can be read. Even $HOME/ldap.conf is not read. My question here is should this code be considered a bug and changed to be less restrictive? I fully appreciate there should be restrictions when in setuid mode but the current code seems too restrictive. init.c: 686 687 openldap_ldap_init_w_sysconf(LDAP_CONF_FILE); 688 689 #ifdef HAVE_GETEUID 690 if ( geteuid() != getuid() ) 691 goto done; 692 #endif 693 694 openldap_ldap_init_w_userconf(LDAP_USERRC_FILE); 695 Norm Green GemTalk Systems LLC

default config file
by Rallavagu Kon 16 Apr '21

16 Apr '21

Hello All, Noticing a difference in behavior of locating config file at the time of startup between 2.4.48 and 2.4.58. The 2.4.48 is a ubuntu supplied package while 2.4.58 is compiled with following options. ./configure --prefix=/opt/openldap \ --sysconfdir=/etc/ldap \ --localstatedir=/opt/openldap/var \ --libexecdir=/opt/openldap/lib \ --disable-static \ --enable-debug \ --with-tls=openssl \ --with-cyrus-sasl \ --enable-dynamic \ --enable-crypt \ --enable-spasswd \ --enable-slapd \ --enable-modules \ --enable-rlookups \ --enable-backends=mod \ --disable-ndb \ --disable-sql \ --disable-shell \ --disable-bdb \ --disable-hdb \ --enable-overlays=mod When started the slaps in debug mode, I see the following for 2.4.48 6077b590 backend_startup_one: starting "cn=config" 6077b590 ldif_read_file: read entry file: "/etc/ldap/slapd.d/cn=config.ldif” Essentially, looking for “cn=config”. However, after replacing the binaries with compiled version for 2.4.58, 6077b37d could not stat config file "/etc/ldap/slapd.d/slapd.conf": No such file or directory (2) I clearly notice that existing configuration file(s) are not considered with 2.4.58. Wondering what is the difference and how can I use the existing configuration files. Thanks
