olcAccess: Regex questions for "departments" and there admins
by Denny Fuchs 14 Nov '13

14 Nov '13

hi, I plan the new ACL layout for our Wheezy LDAP server. Our layout: Main suffix: dc=example,dc=com than the first department: ou=department1,dc=example,dc=com ou=people,ou=department1,dc=example,dc=com uid=foobar,ou=people,ou=department1,dc=example,dc=com [...] ou=groups,ou=department1,dc=example,dc=com gid=students,ou=groups,ou=department1,dc=example,dc=com [...] ou=roles,ou=department1,dc=example,dc=com cn=mail,ou=roles,ou=department1,dc=example,dc=com cn=admins,ou=roles,ou=department1,dc=example,dc=com ou=services,ou=department1,dc=example,dc=com ou=mail,ou=services,ou=department1,dc=example,dc=com cn=aliases,ou=mail,ou=services,ou=department1,dc=example,dc=com [...] next department2, the same: ou=department2,dc=example,dc=com ou=people,ou=department2,dc=example,dc=com uid=foobar,ou=people,ou=department2,dc=example,dc=com [...] [...] .... complete the same one, as department1 Now I stuck on the ACLs. I want to make use of RegEx, so that every department has its own roles, groups and admins and access only to there (for example) services. What I already have: {0}to attrs=userPassword,shadowLastChange,sambaLMPassword,sambaNTpassword by self =xw by anonymous auth by * none {1}to dn.regex="uid=(.+),ou=people,ou=(.+),dc=example,dc=com$" attrs="myFB,myStudiengang,gender,myMatrikel,myTudUserUniqueID" by self read by * none {2}to dn.regex="uid=(.+),ou=people,ou=(.+),dc=example,dc=com$" attrs="mail,myMailalias,myMailDomain,myNoMail" by self read by dn.regex="cn=mail,ou=roles,ou=$2,dc=example,dc=com$" read by * none {3}to dn.regex="^(.+,)?ou=mail,ou=services,ou=(.+)?,dc=example,dc=com$" by dn.regex="cn=mail,ou=roles,ou=$2,dc=example,dc=com$" read {4}to dn.regex="^(.+,)?ou=services,ou=(.+,)?dc=example,dc=com$" by * none {5}to * by dn.base="cn=Admin,dc=example,dc=com" write by * read {6}to dn.base="dc=example,dc=com" by self write by dn.base="cn=Admin,dc=example,dc=com" write by * read I'm able to read the subtree: "ou=mail,ou=services,ou=department1,dc=example,dc=com" only with the authenticated user "cn=mail,ou=roles,ou=department1,dc=example,dc=com" and "ou=mail,ou=services,ou=department2,dc=example,dc=com" with authenticated user "cn=mail,ou=roles,ou=department2,dc=example,dc=com" and I can't search with user from ou=department2 the service tree from ou=department1 :-) But, why I can't see the "ou=services,ou=department2,dc=example,dc=com" ? Just for me to know, where I have a problem ... for the services (Postfix in most cases) it isn't important, that they can't see the "ou=services" Also I want to make sure, that every department "admin group" (cn=admins,ou=roles,ou=<department>,dc=example,dc=com -> groupOfUniqueNames) can do everything under there (and only) three ou=<department>,ou=example,ou=com so, any tipps are welcome :-) cu denny pages I have already open: http://www.openldap.org/doc/admin24/access-control.html http://wiki.mandriva.com/fr/uploads/3/3a/Mandriva-dit-access-template.conf http://www.openldap.org/devel/admin/slapdconf2.html

OpenLdap and Kerberos for oVirt on f19
by Piotr Kliczewski 14 Nov '13

14 Nov '13

Hello everyone, I working on configuring OpenLdap 2.4.36 with kerberos for oVirt running on f19. I follow following instruction: https://bugzilla.redhat.com/show_bug.cgi?id=967327#c5 Please note that the instruction was written for f18. In order to have step 18 working from command line I had to set SASL_NOCANON to off. The reason was that I got: ldap_sasl_interactive_bind_s: Invalid credentials (49) additional info: SASL(-13): authentication failure: GSSAPI Failure: gss_accept_sec_context When SASL_NOCANON is off I can search the ldap but have the same issue from java code: I got javax.naming.AuthenticationException: [LDAP: error code 49 - SASL(-13): authentication failure: GSSAPI Failure: gss_accept_sec_context]. Have this when connecting using engine-manage-domains (http://gerrit.ovirt.org/gitweb?p=ovirt-engine.git;a=blob;f=backend/manager/… line 84). Can you please point me where is my config issue? I copied engine-devel for reference. Thanks, Piotr

"dn: cn=admin,cn=config" adding problem
by Oleg 13 Nov '13

13 Nov '13

Hello. Our slapd listens on outer interfaces and i want to create an access rule for rootdn to allow admin access only from 127.0.0.1 ip. So, i try to add "dn: cn=admin,cn=config" record to config database: ~# cat admin.ldif dn: cn=admin,cn=config objectClass: person cn: admin sn: admin userPassword: 1 ~# ldapadd -xWD 'cn=admin,cn=config' -f admin.ldif Enter LDAP Password: adding new entry "cn=admin,cn=config" ldap_add: Object class violation (65) I got no extra info, just this. According to core.schema mandatory fields are only cn and sn. So, i don't understand why i see this error. Can anybody help me? Thanks.

TLS_REQCERT and no server certificate
by Jan Synacek 13 Nov '13

13 Nov '13

Hello, quoting ldap.conf(5): TLS_REQCERT <level> ... try The server certificate is requested. If no certificate is provided, the session proceeds normally. If a bad certificate is provided, the session is immediately terminated. ... I'd like to try the "If no certificate is provided" part, but can't manage to do so. I tried configuring the server to 1) not use any CA certificate or server certificate, 2) only use the CA certificate without any server certificate, 3) specify CA certificate dir with no certs in it, 4) specify CA certificate dir with a valid CA cert and no server certs. In any case, the client (ldapsearch) doesn't even connect to the server, stating either "SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure" or simply failing to connect with "Can't contact LDAP server (-1)". The server is listening on ldap and ldaps. I tested this using both ldaps and StartTLS. That leads me to a conclusion that what I'm trying to achieve is not achievable and that the manpage should be changed. Is the manpage wrong or is there any other way I can test the client with no server certificate provided? Cheers, -- Jan Synacek Software Engineer, Red Hat

Q: syntax 1.3.6.1.4.1.1466.115.121.1.51
by Ulrich Windl 12 Nov '13

12 Nov '13

Hi! I see that core.schema defines: --- attributetype ( 2.5.4.22 NAME 'teletexTerminalIdentifier' DESC 'RFC2256: Teletex Terminal Identifier' SYNTAX 1.3.6.1.4.1.1466.115.121.1.51 ) --- However I cannot locate the syntax for the OID. It's mentioned in secion 6.5 of RFC 2256, however. How is an LDAP client expected to resolve this? I see the following syntaxes defines in the LDAP schema: DB<17> print sort map { $_->{name} . "\n" } $s->all_syntaxes 1.2.36.79672281.1.5.0 1.3.6.1.1.1.0.0 1.3.6.1.1.1.0.1 1.3.6.1.1.16.1 1.3.6.1.4.1.1466.115.121.1.10 1.3.6.1.4.1.1466.115.121.1.11 1.3.6.1.4.1.1466.115.121.1.12 1.3.6.1.4.1.1466.115.121.1.14 1.3.6.1.4.1.1466.115.121.1.15 1.3.6.1.4.1.1466.115.121.1.22 1.3.6.1.4.1.1466.115.121.1.24 1.3.6.1.4.1.1466.115.121.1.26 1.3.6.1.4.1.1466.115.121.1.27 1.3.6.1.4.1.1466.115.121.1.28 1.3.6.1.4.1.1466.115.121.1.34 1.3.6.1.4.1.1466.115.121.1.36 1.3.6.1.4.1.1466.115.121.1.38 1.3.6.1.4.1.1466.115.121.1.39 1.3.6.1.4.1.1466.115.121.1.4 1.3.6.1.4.1.1466.115.121.1.40 1.3.6.1.4.1.1466.115.121.1.41 1.3.6.1.4.1.1466.115.121.1.44 1.3.6.1.4.1.1466.115.121.1.45 1.3.6.1.4.1.1466.115.121.1.49 1.3.6.1.4.1.1466.115.121.1.5 1.3.6.1.4.1.1466.115.121.1.50 1.3.6.1.4.1.1466.115.121.1.52 1.3.6.1.4.1.1466.115.121.1.6 1.3.6.1.4.1.1466.115.121.1.7 1.3.6.1.4.1.1466.115.121.1.8 1.3.6.1.4.1.1466.115.121.1.9 1.3.6.1.4.1.4203.666.11.10.2.1 Regards, Ulrich

OpenLDAP on CF disk
by richard lucassen 11 Nov '13

11 Nov '13

Hello list, I want to migrate some OpenLDAP servers from 3.5" disks to CF-disks. The data in the OpenLDAP is only updated once a month or so. It is just an "99%-read-only" LDAP implementation. However, with a standard Debian install, some files in the /var/lib/ldap directory are updated upon each query: # ls -altr -rw-r--r-- 1 openldap openldap 96 2008-11-19 11:45 DB_CONFIG drwxr-xr-x 28 root root 4096 2008-12-03 15:03 .. -rw------- 1 openldap openldap 8192 2013-04-08 10:50 cn.bdb -rw------- 1 openldap openldap 24576 2013-09-29 13:49 objectClass.bdb -rw------- 1 openldap openldap 180224 2013-09-29 13:49 id2entry.bdb -rw------- 1 openldap openldap 8192 2013-09-29 13:49 entryUUID.bdb -rw------- 1 openldap openldap 8192 2013-09-29 13:49 entryCSN.bdb -rw------- 1 openldap openldap 36864 2013-09-29 13:49 dn2id.bdb -rw------- 1 openldap openldap 1168654 2013-10-17 09:40 log.0000000001 -rw------- 1 openldap openldap 24576 2013-11-07 05:45 __db.005 -rw------- 1 openldap openldap 98304 2013-11-07 05:45 __db.003 -rw-r--r-- 1 openldap openldap 4096 2013-11-07 05:45 alock drwx------ 2 openldap openldap 4096 2013-11-07 05:45 accesslog drwx------ 3 openldap openldap 4096 2013-11-07 05:45 . -rw------- 1 openldap openldap 565248 2013-11-07 11:30 __db.004 -rw------- 1 openldap openldap 2629632 2013-11-07 11:30 __db.002 -rw------- 1 openldap openldap 8192 2013-11-07 11:30 __db.001 Apparently the cluster is doing some synchronizing at 05:45 in the morning, but that's once a day. My concern is the files called __db.001 __db.002 __db.004 Is there a simple way to prevent OpenLDAP from updating these files at each query?

How can i add mailacceptinggeneralid and maildrop attirbutes to use postfix with openldap ? I tried to adding a schema like (into /etc/ldap/schema) # # postfix.schema - basic attributes based on default queries # postfix will make for alias and virtual account lookups # I don't think there is an official postfix schema out there, # but if there is, this most certainly is not it. # # leah(a)frauerpower.com # # mailacceptinguser and mailAccount added by Barrie Bremner < bjb(a)netcraft.com> # attributetype ( 1.3.6.1.4.1.25260.1.000 NAME 'mailacceptinggeneralid' DESC 'Defines an address that we accept mail for' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) attributetype ( 1.3.6.1.4.1.25260.1.001 NAME 'maildrop' DESC 'Defines the address mail goes to' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) attributetype ( 1.3.6.1.4.1.25260.1.002 NAME 'mailacceptinguser' DESC 'Defines if this user accepts mail' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) objectClass ( 1.3.6.1.4.1.25260.1.1.100 NAME 'virtualaccount' DESC 'Holds mail info for a virtual account' STRUCTURAL MUST ( owner $ mailacceptinggeneralid $ maildrop $ cn ) ) objectClass ( 1.3.6.1.4.1.25260.1.1.101 NAME 'maillist' DESC 'Virtual account for holding mailing list info' STRUCTURAL MUST ( mailacceptinggeneralid $ maildrop $ cn ) ) objectClass ( 1.3.6.1.4.1.25260.1.1.102 NAME 'mailAccount' DESC 'Email account details' AUXILIARY MUST ( mailacceptinguser $ maildrop $ cn ) MAY ( mailacceptinggeneralid ) ) and add a line into /usr/share/slapd/slapd.conf " include /etc/ldap/schema/inetorgperson.schema" But i am geting ldap_add: Invalid syntax (21) additional info: objectClass: value #3 invalid per syntax when i try to add an object objectClass:mailAccount Where am i wrong?
