Use of olcTLSECName directive returns ‘wrong attibuteType’ error
by Lemons, Terry 21 Apr '23

21 Apr '23

Hi I’m attempting to modify the TLS ciphers that are used in an openldap2-2.4.41-22.16.1.x86_64 environment in our lab, running on SLES 12 SP5. I’ve used the following command to set the cipher list value to the returned value of ‘openssl ciphers HIGH’: ldpdd041:/tmp # cat set-ciphersuite.ldif dn: cn=config changetype: modify add: olcTLSCipherSuite olcTLSCipherSuite: HIGH ldpdd041:/tmp # ldapmodify -H ldapi:// -Y EXTERNAL -f set-ciphersuite.ldif SASL/EXTERNAL authentication started SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth SASL SSF: 0 modifying entry "cn=config" ldpdd041:/tmp # openssl ciphers HIGH ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:SRP-DSS-AES-256-CBC-SHA:SRP-RSA-AES-256-CBC-SHA:SRP-AES-256-CBC-SHA:DH-DSS-AES256-GCM-SHA384:DHE-DSS-AES256-GCM-SHA384:DH-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA256:DH-RSA-AES256-SHA256:DH-DSS-AES256-SHA256:DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:DH-RSA-AES256-SHA:DH-DSS-AES256-SHA:DHE-RSA-CAMELLIA256-SHA:DHE-DSS-CAMELLIA256-SHA:DH-RSA-CAMELLIA256-SHA:DH-DSS-CAMELLIA256-SHA:AECDH-AES256-SHA:ADH-AES256-GCM-SHA384:ADH-AES256-SHA256:ADH-AES256-SHA:ADH-CAMELLIA256-SHA:ECDH-RSA-AES256-GCM-SHA384:ECDH-ECDSA-AES256-GCM-SHA384:ECDH-RSA-AES256-SHA384:ECDH-ECDSA-AES256-SHA384:ECDH-RSA-AES256-SHA:ECDH-ECDSA-AES256-SHA:AES256-GCM-SHA384:AES256-SHA256:AES256-SHA:CAMELLIA256-SHA:PSK-AES256-CBC-SHA:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:SRP-DSS-AES-128-CBC-SHA:SRP-RSA-AES-128-CBC-SHA:SRP-AES-128-CBC-SHA:DH-DSS-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:DH-RSA-AES128-GCM-SHA256:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES128-SHA256:DHE-DSS-AES128-SHA256:DH-RSA-AES128-SHA256:DH-DSS-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA:DH-RSA-AES128-SHA:DH-DSS-AES128-SHA:DHE-RSA-CAMELLIA128-SHA:DHE-DSS-CAMELLIA128-SHA:DH-RSA-CAMELLIA128-SHA:DH-DSS-CAMELLIA128-SHA:AECDH-AES128-SHA:ADH-AES128-GCM-SHA256:ADH-AES128-SHA256:ADH-AES128-SHA:ADH-CAMELLIA128-SHA:ECDH-RSA-AES128-GCM-SHA256:ECDH-ECDSA-AES128-GCM-SHA256:ECDH-RSA-AES128-SHA256:ECDH-ECDSA-AES128-SHA256:ECDH-RSA-AES128-SHA:ECDH-ECDSA-AES128-SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:CAMELLIA128-SHA:PSK-AES128-CBC-SHA ldpdd041:/tmp # So I had expected to see that all of these ciphers were being offered for use by the OpenLDAP server; instead, I see that only a subset of the list is offered: sslyze ldpdd041.hop.lab.emc.com:636 . . . * TLS 1.0 Cipher Suites: Attempted to connect using 80 cipher suites.

Rather than mess around with generating the DH param file, etc., I’d like to use ECDHE-based ciphers. According to p. 160 of https://www.openldap.org/doc/admin24/OpenLDAP-Admin-Guide.pdf, the ‘TLSECName’ directive allows an ECDHE curve to be specified. When I tried to enable use of the directive, I received a ‘wrong attibuteType’ error: ldpdd041:/tmp # cat set-ecname.ldif dn: cn=config changetype: modify add: olcTLSECName olcTLSECName : secp384r1 ldpdd041:/tmp # ldapmodify -H ldapi:// -Y EXTERNAL -f set-ecname.ldif SASL/EXTERNAL authentication started SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth SASL SSF: 0 ldapmodify: wrong attributeType at line 4, entry "cn=config" ldpdd041:/tmp # Does OpenLDAP 2.4.41 not support this directive?

How to update UNIX+Samba password?
by Jan Andersen 14 Apr '23

14 Apr '23

I have OpenLDAP 2.4.57 on a Debian 11 server and Samba 4.13.13, on another Debian 11 system. When I create a new user in LDAP Account Manager (LAM), I can log in to the linux client systems, and I can connect using smbclient; and I can change the password successfully from LAM for both Samba and Linux. However, I can't do the same from the linux command line with 'passwd'. I have found several articles pointing me to smbk5pwd, which I have installed and configured according to https://bangdash.space/2021/01/syncing-ldap-passwords-with-samba/ - but it doesn't make a difference. Clearly I have not set it up correctly; I would be grateful if someone with more insight than myself could help me find the problem. I have run a session where user 'zzuser' changed their password from linux and the server ran: /usr/sbin/slapd -h "ldap:/// ldapi:/// ldaps:///" -g openldap -u openldap -F /etc/ldap/slapd.d -d -1 It generated 42715 lines of output, which I have saved, but I hesitate to dump it here. However, please let me know what information you need to help me.

Argon2-Support or secure hashing
by Lukas Adrian Kron 14 Apr '23

14 Apr '23

Hello, I am trying to use Argon2 or PBKDF2_SHA256 as a secure password hashing function. Since two weeks I am trying to get this to work with reading a lot of information on the internet and I just cannot get it to work. I am using Ubuntu 20.04 LTS, installed with slapd, ldap-utils, argon2 and trying to set it in the cn=config Frontend setting. @(#) $OpenLDAP: slapd (Ubuntu) (May 12 2022 13:11:05) $ Debian OpenLDAP Maintainers <pkg-openldap-devel(a)lists.alioth.debian.org> This is the version that is installed from Slapd and when I try to set pw-argon2, {ARGON2}, pw-argon2.so... I tried a lot and it tells me no hash found. If I try {MD5} it works without problems. As there is no other secure usable password hashing installed the LDAP Server is right now insecure and I cannot move it to production Please does someone has any idea? Many kind regards, Lukas

meaning of bind_ssf
by Stefan Kania 14 Apr '23

14 Apr '23

Hi to all, when I connect to openldap, with simple-bind I see: ----------- mech=SIMPLE bind_ssf=0 ssf=256 ----------- When I connect to openldap with GSSAPI I see: ----------- mech=GSSAPI bind_ssf=56 ssf=256 ----------- So I uses strong-bind via GSSAPI there is no place where I can find anything about "bind_ssf". So what ist bind_ssf stands for? I only found: transport_ssf=<n> tls_ssf=<n> sasl_ssf=<n> Another strange thing (to me ;-) ) The openldap admin guide is telling me: ---------------- The server uses Security Strength Factors (SSF) to indicate the relative strength of protection. A SSF of zero (0) indicates no protections are in place. A SSF of one (1) indicates integrity protection are in place. A SSF greater than one (>1) roughly correlates to the effective encryption key length. For example, DES is 56, 3DES is 112, and AES 128, 192, or 256. ---------------- in my kdc.conf I have: --------------- supported_enctypes = aes256-cts-hmac-sha1-96:normal aes128-cts-hmac-sha1-96:normal --------------- So no DES with a key-length of 56 is defined. Same when I look at the key from my user I'm using to connect. The infos about the user is telling me in kadmin ---------------- Key: vno 1, aes256-cts-hmac-sha1-96 Key: vno 1, aes128-cts-hmac-sha1-96 ---------------- So why is the log telling me ssf=56? Stefan

Slow Search?

Hi all, I am new to OpenLDAP, recently I am following the official quick-start guide and finished the installation part. However when configuring the database which is step 9 in the guide su root -c /usr/local/sbin/slapadd -n 0 -F /usr/local/etc/slapd.d -l /usr/local/etc/openldap/slapd.ldif I got the error: slapadd: bad configuration directory!

How to build argon2.so ?
by Scott Classen 06 Apr '23

06 Apr '23

Hello, According to: servers/slapd/pwmods/README.argon2 Building -------- 1) Customize the OPENLDAP variable in Makefile to point to the OpenLDAP source root. For initial testing you might also want to edit DEFS to define SLAPD_ARGON2_DEBUG, which enables logging to stderr (don't leave this on in production, as it prints passwords in cleartext). 2) Run 'make' to produce argon2.so 3) Copy argon2.so somewhere permanent. 4) Edit your slapd.conf (eg. /etc/ldap/slapd.conf), and add: moduleload ...path/to/argon2.so 5) Restart slapd. When I run make from within servers/slapd/pwmods/ I get the following error: [user@machine openldap-2.6.4]# cd servers/slapd/pwmods/ [user@machine pwmods]# make make: *** No rule to make target 'dummyvalue', needed by 'all-common'. Stop. I’m not sure what “dummyvalue” is supposed to be so I commented out line 288 in servers/slapd/pwmods/Makefile # LIBRARY = dummyvalue And get this error: [user@ machine pwmods]# make /bin/sh ../../../libtool --tag=disable-static --mode=compile cc -g -O2 -I../../../include -I../../../include -I.. -I./.. -DSLAPD_IMPORT -c version.c libtool: compile: cc -g -O2 -I../../../include -I../../../include -I.. -I./.. -DSLAPD_IMPORT -c version.c -fPIC -DPIC -o .libs/version.o version.c:1:6: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘:’ token usage: mkversion [-c] [-s] [-p package] [-v version] application ^ make: *** [Makefile:310: version.lo] Error 1 Any help in generating argon2.so would be greatly appreciated. If I’m somehow getting deeper in the weeds than I need to with the new OpenLDAP version 2.6.4 in order to support {ARGON2} hashes please let me know. Import of my slapd.ldif file is bonking on: olcPasswordHash: {ARGON2} So as with previous versions of OpenLDAP I assumed I would need to build and load the argon2 module manually.
