How to assign a password policy to a group of users, in one go
by Rodrigo Coutinho 25 Feb '14

25 Feb '14

Hi again, I've finally managed to setup the password policy, but only statically (ran configure again). Have defined two password policies, one for all (default) and another for a specific group of users. The question now is: Can I assign a password policy to a group of users (cn=some_group,ou=groups,dc=xxx,dc=local)in one go, or must I assign to each user individualy the pwdPolicySubentry? I have searched, and although slapo states that it can be done, no example is provided. Thank you in advance A transmiss�o de mensagens por e-mail n�o � absolutamente segura ou livre de erros.

libldap "Happy Eyeballs" support (aka Fast Fallback or ipv4/ipv6 dual-stack)
by Žarko Milenković 25 Feb '14

25 Feb '14

Hi all, I would like to have Happy Eyeballs<http://en.wikipedia.org/wiki/Happy_eyeballs> algorithm (more details here<http://tools.ietf.org/html/rfc6555>) implemented for all network communication in my application. Because I'm using libldap for searching openldap server I'm not quite sure does library already support this or would I need to implement it myself? To further clarify, I have following scenario: ldap server on myoldap.organization.org that listens for both ipv6 and ipv4 connections. Clients connect to it using libldap. Does libldap have support to automatically choose ipv6 over ipv4 or vice versa? If yes, how is choice made? Is ipv6 always preferred if available or does better connection win? If no, then I know the way I need to go. The only thing to add there is that I would be willing to add this support to libldap. Thanks, Žarko

dynlist groups not usable in ACLs?
by DRVTiny 24 Feb '14

24 Feb '14

OpenLDAP 2.4.39, amd64, debian 7 When i use the group with only static members in "by group/groupOfNames/member" clause - all works perfectly But when i'm trying to use in ACL definition dynamic members in 1:1 identicaly group - it doesnt work at all and in slapd debug output i see: --- 530b1a22 dnMatch -40 "dc=ru" "uid=konovalov-aa,ou=people,dc=svc,dc=ot,dc=ru" --- where "dc=ru" is one static member of this group (all others is dynamic members and it is not compared to "uid=konovalov-aa,ou=people,dc=svc,dc=ot,dc=ru" at all). It is very strange behavior, because official documentation says that: --- Dynamic Groups are also supported in Access Control. Please see slapo-dynlist(5) and the Dynamic Lists overlay section. --- Any comments? Can i use dynlist'ed groups in OpenLDAP ACL?

strategy for getting groupOfNames (AD) and posixAccount (Unix) to coexist?
by Jefferson Davis 24 Feb '14

24 Feb '14

This has been beating me like a red-headed stepchild... In the AD world, groupOfNames is expected (in combination with the member attribute, provides for reverse group resolution, ie users by group membership AND groups by member inclusion). On the unix side of the fence, groups REQUIRE a gidNumber in order to resolve group membership, using posixGroup structural OC in conjunction with memberUID. In attempting to future-proof our ldap services, and to accommodate the AD-Focused nature of commercial products, I'm attempting to get this to all work automatically, ie use the same group setup for both (probably naive and ill-advised?). But you CANNOT have multiple structural objectclasses in a single entry. So these requirements put group structures in direct opposition of one another. Has anyone resolved this successfully, and if so, how? Overlays (which ones, examples)? Schema mods (examples?) Splitting groups off as unix groups vs windows groups (sync could get ugly) and could run into other issues with respect to file and dir permissions. I also need to avoid breaking smbldap-tools, which at the moment appears NOT to support the groupofnames model. Building this on CentOS 6, OpenLDAP 2.4.23-34, and migrating from older OpenLDAP version. I'm somewhat open to considering a different LDAP service (389/Apache/OpenDJ) though I've found java to be a resource pig in the extreme, and would prefer to avoid if possible. If you have this working I would love to see the relevant configuration files. -- Jefferson K Davis Technology and Information Systems Manager Standard School District 1200 North Chester Ave Bakersfield, CA 93308 661.392.2110 ext 120 (office) http://district.standard.k12.ca.us District Users: Click here to report technology issues

Relay recipient postfix via ldap exception email address
by Rony 23 Feb '14

23 Feb '14

I make postfix relay recipient via ldap and I want an exception email addresses can not look up but have not been successful, my configuration server_host = 1.1.1.1.1 ldap_search_base = o = example, c = com bind = no query_filter = (| (mail =% s) (mailAlternateAddress =% s)) (! (mail = group(a)example.com))) result_attribute = mail I want group(a)example.com can not look up, but have not been successful, how correct configuration?

Cyrus IMAPD + virtual domains + SASL + OpenLDAP ldapdb
by Nels Lindquist 21 Feb '14

21 Feb '14

I'm attempting to configure Cyrus IMAPD with ldapdb for SASL authentication. As I'm using virtual domains, I need users to be able to authenticate using their e-mail addresses, or just a bare userid for the default domain. I'm having some trouble getting everything working[1]. Based on this documentation extract from Cyrus SASL, I've been primarily focussing on the OpenLDAP configuration: "Unlike other LDAP-enabled plugins for other services that are common on the web, this plugin does not require you to configure DN search patterns to map usernames to LDAP DNs. This plugin requires SASL name mapping to be configured on the target slapd. This approach keeps the LDAP-specific configuration details in one place, the slapd.conf, and makes the configuration of remote services much simpler." I've set up a number of olcAuthzRegexp entries similar to (from the OpenLDAP 2.4 admin guide): "A more complex site might have several realms in use, each mapping to a different subtree in the directory. These can be handled with statements of the form: # Match Engineering realm authz-regexp uid=([^,]*),cn=engineering.example.com,cn=digest-md5,cn=auth ldap:///dc=eng,dc=example,dc=com??one?(&(uid=$1)(objectClass=person)) # Match Accounting realm authz-regexp uid=([^,].*),cn=accounting.example.com,cn=digest-md5,cn=auth ldap:///dc=accounting,dc=example,dc=com??one?(&(uid=$1)(objectClass=person)) # Default realm is customers.example.com authz-regexp uid=([^,]*),cn=digest-md5,cn=auth ldap:///dc=customers,dc=example,dc=com??one?(&(uid=$1)(objectClass=person))" However, from what I can determine I'm not getting any realm component in the searches coming through. The "default" realm configuration works when I use a bare userid to authenticate, but when using a full e-mail address, that comes through as "uid=example(a)example.com,cn=[authmech],cn=auth". That said, I haven't found a LogLevel which includes AuthzRegexp processing; I've tried various settings, but the closest I've come is logging the resulting bind requests (eg. BIND dn="uid=example,ou=people,dc=example,dc=com" mech=DIGEST-MD5 sasl_ssf=128 ssf=128). So my question is, how is the realm determined in such a scenario? Do I need to design olcAuththzRegexp entries to determine the realm based on the e-mail address supplied? If so, how does that information get passed back to Cyrus IMAPD so that the correct virtual domain is selected? Is there an appropriate olcLogLevel to see detailed olcAuthzRegexp processing? I'd be grateful for any suggestions or references to documentation, etc. I've done some searching of the mailing list archives to little avail. In case it matters, this is on CentOS 6.5 (x86_64) with stock OpenLDAP 2.4.23 and Cyrus SASL 2.1.23 packages, plus Cyrus IMAPD 2.4.17 built from Simon Matter's SRPM. [1] I *am* able to get authentication + virtual domains working with saslauthd, but I'd like to be able to support non-plaintext auth mechanisms. ---- Nels Lindquist

RE: Syncrepl and mmr
by Quanah Gibson-Mount 20 Feb '14

20 Feb '14

Hi John, SIDs (server IDs) must be unique across servers. RIDs (replication IDs) must be unique inside a single server. So the answer to your question is essentially "no". If you email me your full cn=config db bits from both servers (minus passwords), there's some cleanup on them I can send back. The serverID: 1 <URI> bit is only necessary if you are doing cn=config replication, which you are not doing. If you are going to use the <#> <URI> form, then the <URI> must EXACTLY MATCH the arguments slapd is being started with. Personally, since I do not do cn=config replication, and the URIs are customizable by customers, I go with the much simpler: olcServerID: <#> form. Then each server only has a single value for olcServerID, which is its specific serverID. This way I never have to worry that MMR replication is going to get mesed up because of URI changes. --Quanah --On Tuesday, February 18, 2014 10:09 AM -0500 "Borresen, John - 0442 - MITLL" <John.Borresen(a)ll.mit.edu> wrote: > All, > > The long weekend didn't help...still at a loss.

AttributeDescription contains inappropriate characters
by Kamran Khan 20 Feb '14

20 Feb '14

Hi All, I'm a bit new to OpenLDAP, and I'm not quite sure what went wrong. I installed OpenLDAP because it was a prerequisite of Moab. After installing OpenLDAP and Moab yesterday, I had everything working just fine. I rebooted the cluster, and now OpenLDAP is not happy. ============================================================ [root@USDTWCLUS01 ~]# service slapd start Checking configuration files for slapd: [FAILED] <= str2entry: str2ad(o): AttributeDescription contains inappropriate characters slaptest: bad configuration file! ============================================================ I understand that something in my configuration must be messed up, but I am really unsure where there error is occuring. I'm unsure where my 'str2entry's are. Any help is greatly appreciated. Like I said, I had it working just fine yesterday, and after a reboot it didn't like something. Thanks. -- Kamran Khan PSSC Labs HPC Software Technical Engineer
