"GSSAPI Error: No credentials were supplied ... unknown mech-code 0 for mech unknown"
by Braiam 15 May '20

15 May '20

Hi, I'm trying to get slapd to use heimdal kerberos to provide a single authentication backend for my network. I've followed the Administrator's Guide on SASL[1] and cyrus faq entry about connecting OpenLDAP with GSSAPI[2]. I'm stuck at the what I believe is a misunderstanding from my part. I believe when I use -Y GSSAPI I should be using my braiam/admin credentials, but according to SASL facility in slapd I'm not providing any. strace confirms that it reads the /tmp/krb5cc_1000 file correctly. I'm very confused as to how to proceed since most of the relevant results point to having not kinit'd. I'm using Debian stable, slapd=2.4.47+dfsg-3+deb10u1, libsasl2-modules-gssapi-heimdal=2.1.27+dfsg-1+deb10u1. debian@ldap01:~$ sudo ktutil -k /etc/krb5.keytab list /etc/krb5.keytab: Vno Type Principal Aliases 4 aes256-cts-hmac-sha1-96 host/ldap01.example.com(a)EXAMPLE.COM 4 des3-cbc-sha1 host/ldap01.example.com(a)EXAMPLE.COM 4 arcfour-hmac-md5 host/ldap01.example.com(a)EXAMPLE.COM 9 aes256-cts-hmac-sha1-96 ldap/ldap01.example.com(a)EXAMPLE.COM 9 des3-cbc-sha1 ldap/ldap01.example.com(a)EXAMPLE.COM 9 arcfour-hmac-md5 ldap/ldap01.example.com(a)EXAMPLE.COM debian@ldap01:~$ klist Credentials cache: FILE:/tmp/krb5cc_1000 Principal: braiam/admin(a)EXAMPLE.COM Issued Expires Principal May 12 20:34:05 2020 May 13 20:34:05 2020 krbtgt/EXAMPLE.COM(a)EXAMPLE.COM May 12 20:34:11 2020 May 13 20:34:05 2020 ldap/ldap01.example.com(a)EXAMPLE.COM debian@ldap01:~$ ldapsearch -LLL -Y GSSAPI -s "base" -b "" supportedSASLMechanisms -H $ldap_host SASL/GSSAPI authentication started ldap_sasl_interactive_bind_s: Other (e.g., implementation specific) error (80) additional info: SASL(-1): generic failure: GSSAPI Error: No credentials were supplied, or the credentials were unavailable or inaccessible.

Help for setting-up an ldap-proxy
by lists＠zxt10d.de 14 May '20

14 May '20

Hello, I'm pretty new to this list, and maybe/hopefully someone could help ... I work at a chair at a german university, and we would like to use the central AD of theat university for our chair - by using a ldap-proxy system, so that there's only one connection to the central AD, and not ~70 (all of our computers, etc.). I can search the AD by using this (modified) command: ldapsearch -LLL "(cn=FIRSTNAME LASTNAME)" -H ldaps://ldap.UNIVERSITY.de -b dc=university,dc=de -D cn=special,ou=group,dc=university,dc=de -W For locally installed applications I can use this /etc/pam_ldap.conf: uri ldaps://ldap.university.de host ldap.university.de base ou=group,ou=hosts,dc=university,dc=de ldap_version 3 binddn cn=special,ou=group,dc=university,dc=de bindpw password pam_password crypt ssl start_tls ssl on To set-up the local ldap-proxy, I tried to follow this description, but it won't work (and I guess its not realy correct, as the config-file is there twice): https://doc.owncloud.com/server/admin_manual/configuration/ldap/ldap_proxy_… When running "slaptest -f /etc/ldap/slapd.conf" I get these errors: 5ebd3ec5 /etc/ldap/slapd.conf: line 102: warning, source attributeType 'dn' should be defined in schema 5ebd3ec5 PROXIED attributeDescription "DN" inserted. 5ebd3ec5 hdb_db_open: warning - no DB_CONFIG file found in directory /var/lib/ldap: (2). Expect poor performance for suffix "ou=group,ou=hosts,dc=university,dc=de". 5ebd3ec5 hdb_db_open: database "ou=lsafp,ou=hosts,dc=university,dc=de": db_open(/var/lib/ldap/id2entry.bdb) failed: No such file or directory (2). 5ebd3ec5 backend_startup_one (type=hdb, suffix="ou=group,ou=hosts,dc=university,dc=de"): bi_db_open failed! (2) 5ebd3ec5 backend_startup_one (type=ldap, suffix="ou=group,ou=hosts,dc=university,dc=de"): bi_db_open failed! (2) slap_startup failed (test would succeed using the -u switch) Now my questions: - where and how to put the data to do a query versus the central AD? (binddn & bindpw part) - where to define the local ldap-database? (I guess that has to be created an will be filled automatically...?) The system I'm using is a Debian 10.4 one. slapd -V: @(#) $OpenLDAP: slapd (Apr 20 2020 18:19:54) $ Debian OpenLDAP Maintainers <pkg-openldap-devel(a)lists.alioth.debian.org> Sorry, english is not my native language ... Thanks a lot for reading! ;) Cheers, Torsten

Hello, I'm farely now to OpenLDAP. I have successfully build a connection to an Windows Active Directory with LDAP over Port 389. But when I switch to LDAPS and Port 636 and try a connection via the Softerra LDAP Browser I get the following error: TLS certificate verification: Error, unable to get local issuer certificate TLS: can't connect: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (unable to get local issuer certificate). I have installed the certificate of the Server I want to connect to on my machine. But I still get this error. Does anyone have an idea why this error happens?

Remove duplicate ppolicy overlay
by Côme Chilliet 06 May '20

06 May '20

Hello, I have a duplicated ppolicy overlay. If I try to delete it using an LDAP operation on the node under cn=config, I get a 53 error. After searching I found an email on this list ( https://www.openldap.com/lists/openldap-technical/201811/msg00077.html ) which suggest the following procedure: a) slapcat -n 0 -l /tmp/config.ldif b) Remove the duplicate entries from /tmp/config.ldif c) mv /path/to/current/config /path/to/current/config.old;mkdir -p /path/to/current/config d) slapadd -n 0 -l /tmp/config.ldif But this does not work, because when calling slapadd at the end, it complains that there is no slapd.conf. Is there some way to tell slapadd what to do? Or do I need to create a slapd.conf file that I remove after? -- Côme Chilliet FusionDirectory - https://www.fusiondirectory.org
