"ber write failed", followed by slapd not responding
by Chris Down 07 Jan '14

07 Jan '14

Hello, I am having a small problem with an OpenLDAP master at work. Twice today, at seemingly random intervals, it has stopped responding to all queries, and all clients lose connection to the master, immediately after printing the following message in the debug log: Jan 7 10:04:58 ldap slapd[20310]: send_search_entry: conn 1851 ber write failed. There are no more messages printed before or after this for hours. I looked at the source, but it didn't seem particularly illuminating (it looks like this happens when send_ldap_ber() doesn't write anything and returns 0 bytes, but I don't know how to debug that, since there are a lot of conditions there that return 0). I saw this[0] thread, but we are already using 2.4.23 on Debian Squeeze, so it appears to not be the same problem: @(#) $OpenLDAP: slapd 2.4.23 (Dec 16 2012 11:48:44) $ root@carillon:/tmp/buildd/openldap-2.4.23/debian/build/servers/slapd I am not aware of performing any changes to our LDAP configuration recently. How should I go about debugging this? Is this a known issue? I searched openldap-bugs, but I didn't find anything recent that seemed related. Thanks. 0: http://www.openldap.org/lists/openldap-technical/200907/msg00199.html

Re: Search in Active Directory Proxy with multiple level of OU
by Michael Lois 07 Jan '14

07 Jan '14

Thank you for the reply, Dieter. I tried the following config: rwm-suffixmassage "ou=user,dc=company,dc=com" "OU=All Users,dc=internal,dc=company,dc=com" rwm-map attribute uid sAMAccountName Simple searches work ( ldapsearch -W -x -b "ou=user,dc=company,dc=com" uid=michael), but some of our application needs to specify the binding of which OU the user belongs to. From the above example, if we do a search on proxy with "ldapsearch -xW -b "cn=Michael Lois,ou=user,dc=company,dc=com", the proxy would need to translate it into "cn=Michael Lois,ou=Accounting,OU=All Users,dc=internal,dc=company,dc=com" on AD, without the need for user to provide that Michael Lois on the Accounting OU. Is this possible? I think my problem is similar to this one in the older thread in 2009, but seems like this quesiton was still open: http://www.openldap.org/lists/openldap-technical/200902/msg00090.html

DBIS - new IETF drafts to replace NIS and RFC2307
by Mark R Bannister 06 Jan '14

06 Jan '14

In August this year, I submitted some new IETF drafts with the intent that they would replace NIS and RFC2307. It introduces Directory Based Information Services (DBIS). Michael Ströder suggested I post a link to this mailing list. The following article (and further articles on my blog) discuss some of the aspects of DBIS, and link to all of the relevant internet drafts: http://technicalprose.blogspot.co.uk/2013/08/introducing-dbis.html I am currently working on a reference implementation here: http://sourceforge.net/projects/dbis/ This may be coming out of the blue for many of you, and I appreciate you may need some time to read and digest my drafts, and then ask me lots of questions. But my first question to you is, where is the best place for discussion related to these drafts? Is this the mailing list to use? Best regards, Mark Bannister. e: dbis(a)proseconsulting.co.uk

Ldap password policy not throwing different errors
by Idan Fridman 05 Jan '14

05 Jan '14

Hi, I use ppolicy overlay and enabled ppolicy_use_lockout to separate between invalid password and locked accounts. database bdb suffix "dc=openiam,dc=com" rootdn "cn=Manager,dc=openiam,dc=com" rootpw "{SSHA}2ttRoo/t5HuMT2nPxtI6goVUML5R2H9h" # PPolicy Configuration overlay ppolicy ppolicy_default "cn=default,ou=policies,dc=openiam,dc=com" ppolicy_use_lockout ppolicy_hash_cleartext I tried to lock user account by entering wrong password couple of times (pwdMaxFailure) The user is being locked but when I try to login again I still get the same error: Invalid credentials (49) Any idea why i am not getting diffrent error to disticnt between the cases? thanks, ray.

using the deref control
by Arthur de Jong 05 Jan '14

05 Jan '14

Hi list, First off, best wishes for 2014. I've been looking into the deref control that was pointed out here (in the Oracle OpenLDAP PPolicy ppolicy and the hierarchy thread). With some trail and error I got things working so I thought to document what I did in the hopes that it may be useful for other people wanting to use this control. First of all, get a slapd instance running with the deref overlay. With older versions (at least 2.4.31) it was sufficient to load the module to have the relevant control being shown in the root DSE. However, due to ITS#7436 this didn't actually do anything. With later slapd versions (at least 2.4.38) loading the overlay apparently isn't sufficient but you have to also configure it for each database: dn: olcOverlay={1}deref,olcDatabase={1}bdb,cn=config objectClass: olcOverlayConfig olcOverlay: {1}deref In terms of using the API you have to first create a control with ldap_create_deref_control() and pass it along with ldap_search_ext(). After the call to search, free the control again with ldap_control_free(). The control is built up of an array of LDAPDerefSpec structs that contains the attribute name that contains the link and a list of attributes to retrieve from the linked entry (just like you would pass to ldap_search()). A bump in the road here was that ldap_create_deref_control() was broken (reported earlier and already fixed in Git) but ldap_create_deref_control_value() seems to work. Any response entries will have a control available that can be extracted with ldap_get_entry_controls() and parsed with ldap_parse_derefresponse_control() (and freed with ldap_derefresponse_free()). The returned control data is a linked list of LDAPDerefRes structs, one per link attribute value. Each struct contains the attribute name, the original value and a linked list of LDAPDerefVal structs. The DerefVal structs contain per requested attribute from the linked entry (if the entry has the attribute) the attribute name and a list of values. This has been implemented in the development branch of nss-pam-ldapd and will probably land in the next 0.9 release. - adding the request control: http://arthurdejong.org/git/nss-pam-ldapd/commit/?id=547e4792c580b67ec14595… - parsing the response control information: http://arthurdejong.org/git/nss-pam-ldapd/commit/?id=c973834328baa69dbd3352… - complete functionality (merge commit): http://arthurdejong.org/git/nss-pam-ldapd/commit/?id=c6c317ec9efb8190bdc183… Hope this is helpful for someone. -- -- arthur - arthur(a)arthurdejong.org - http://arthurdejong.org/ --

OpenLDAP Multiple User Import
by David Barr 03 Jan '14

03 Jan '14

I have one file that I need to use to import about 50 people, it doesn't like the fact that I have more than one user in the file for some reason. I might have another 200 in the future and need to figure out why it isn't working... Help please. Is my syntax wrong? Did I place something in the wrong order or something more than once that isn't needed. I have included two users, all are the same except the actual username. Help please. # USER ENTRY dn: cn=New.user01,ou=People,dc=test,dc=com uid: NEW.user01 givenName: NEW.user01 objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson userPassword: NEW.user01 sn: NEW.user01 ou: People cn: NEW.user01 objectClass: uidObject objectClass: pwdPolicy pwdAttribute: userPassword objectClass: pwdPolicyChecker pwdMinAge: 86400 pwdMaxAge: 7776002 pwdInHistory: 10 pwdCheckQuality: 2 pwdMinLength: 14 pwdExpireWarning: 432000 pwdGraceAuthNLimit: 0 pwdFailureCountInterval: 120 pwdAllowUserChange: TRUE pwdCheckModule: Standard Policy pwdLockout: FALSE dn: cn=NEW.user02,ou=People,dc=test,dc=com uid: NEW.user02 givenName: NEW.user02 objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson userPassword: NEW.user02 sn: NEW.user02 ou: People cn: NEW.user02 objectClass: uidObject objectClass: pwdPolicy pwdAttribute: userPassword objectClass: pwdPolicyChecker pwdMinAge: 86400 pwdMaxAge: 7776002 pwdInHistory: 10 pwdCheckQuality: 2 pwdMinLength: 14 pwdExpireWarning: 432000 pwdGraceAuthNLimit: 0 pwdFailureCountInterval: 120 pwdAllowUserChange: TRUE pwdCheckModule: Standard Policy pwdLockout: FALSE ldapadd -v -d 1 -D "cn=Admin,dc=test,dc=com" -w test -f /tmp/T/.ldif adding new entry cn=New.user01,ou=People,dc=test,dc=com ldap_add: Type or value exists ldap_add: additional info: objectClass: value #1021 provided more than once ________________________________ CONFIDENTIALITY NOTICE: The information contained in this electronic mail (email) transmission (including attachments), is intended by MCLANE ADVANCED TECHNOLOGIES for the use of the named individual or entity to which it is addressed and may contain information that is privileged, confidential and/or protected as a trade secret.

Search in Active Directory Proxy with multiple level of OU
by Michael Lois 02 Jan '14

02 Jan '14

Hi, We need to setup a openldap proxy to Active Directory. Here is our slapd.conf: database ldap suffix "ou=user,dc=company,dc=com" uri ldap://10.10.10.10/ rebind-as-user idassert-bind bindmethod=simple binddn="cn=openldapuser,ou=Service Accounts,dc=internal,dc=company,dc=com" credentials=******** mode=none idassert-authzFrom "dn.regex:.*" overlay rwm rwm-suffixmassage "OU=All Users,dc=internal,dc=company,dc=com" rwm-map attribute uid sAMAccountName We were trying to query multiple of OU in Active Directory, with the same search string. For example, on AD, user Michael Lois is in "cn=Michael Lois,ou=Accounting,OU=All Users,dc=internal,dc=company,dc=com". With the openldap proxy, we were trying to search Michael with "cn=Michael Lois,ou=user,dc=company,dc=com". From the above slapd config, the following 2 ldapsearch on the openladp proxy server would work: ldapsearch -W -x -b "ou=user,dc=company,dc=com" cn="Michael Lois" ldapsearch -xW -b "cn=Michael Lois,ou=Accounting,ou=user,dc=company,dc=com" But our goal is to make this ldapsearch to give us the same result: ldapsearch -xW -b "cn=Michael Lois,ou=user,dc=company,dc=com" Does anyone know how to search through a proxy with mulitple level of OU in AD? Thank you, Michael
