ppolicy password lockout
by discip＠pjm.com 23 Aug '08

23 Aug '08

Hi, I am having trouble getting password lockout to work with openldap 2.3.32-0.27 on SLES 10 Service Pack 2. I don't see any pwdFailureTime attributes ever show up for the user in question, and the password never locks after bad password attempts. Below is what I've done so far to set this up (note: i have found no errors in any logs so far indicating that the overlay isnt working...) Any help would be greatly appreciated. Thanks, Paul As per the ppolicy documentation on the web, I've added the following lines to my slapd.conf: overlay ppolicy ppolicy_default "cn=stdWebPPolicy,ou=Policies,ou=Config,dc=pjm,dc=com" ppolicy_use_lockout Also, here is the ldif for my policy: dn: cn=stdWebPPolicy,ou=Policies,ou=Config,dc=pjm,dc=com cn: stdWebPPolicy objectClass: pwdPolicy objectClass: person objectClass: top pwdAllowUserChange: TRUE pwdAttribute: 2.5.4.35 pwdCheckQuality: 2 pwdExpireWarning: 600 pwdFailureCountInterval: 30 pwdGraceAuthNLimit: 5 pwdInHistory: 5 pwdLockout: TRUE pwdLockoutDuration: 1800 pwdMaxAge: 0 pwdMaxFailure: 5 pwdMinAge: 0 pwdMinLength: 5 pwdMustChange: FALSE pwdSafeModify: FALSE sn: dummy value And here is the user I am testing against: dn: uid=testuser,ou=People,ou=Test,ou=External,dc=pjm,dc=com objectClass: inetOrgPerson objectClass: organizationalPerson objectClass: person objectClass: top objectClass: pwdPolicy objectClass: posixAccount uid: testuser cn: testuser givenName: Test sn: User pwdAttribute: userPassword gidNumber: 123 homeDirectory: /home/testuser uidNumber: 1234 userPassword: {SSHA}Lz+gz7+HomMnxxq1b+TZpgnxECEbfXs1

slapd with Kerberos and multihomed host
by JUNG, Christian 23 Aug '08

23 Aug '08

Hi, is there a possibility to configure slapd on a multihomed host to authenticate on the different interfaces with different Kerberos principals? Example: one host running linux with two NICs (eth0, eth1) and slapd eth0: IP 10.0.0.23, hostname ldap.sn-1.example.com eth1: IP 10.1.0.42, hostname ldap.sn-2.example.com A client which connects via hostname ldap.sn-1.example.com would request a ticket for the principal ldap/ldap.sn-1.example.com(a)EXAMPLE.COM and one connecting via ldap.sn-2.example.com would request a ticket for ldap/ldap.sn-2.example.com(a)EXAMPLE.COM. Does it suffice to store both keys in the keytab to enable slapd to authenticate for both principals, i.e. does it picks the right key? Which hostname should I define as sasl-host when using SASL to enable plain-text authentication over a SSL-secured connection or is it possible to set multiple sasl-hosts? bye Chris -- phone: +49 6898/10-4987 web : www.saarstahl.de mail : Hofstattstraße 106a D 66333 Voelklingen

Your logs show what IP address those connections are coming from, but since they are being blocked by the changes you made, there's really no data on what client is making those connections. The only person who can track down what clients are trying to bind *without* TLS is you. You may not like that answer, but it isn't going to change. You're original question posed at the end of your email was is this the expected behavior for those settings, and the answer is yes. If you block clients that are not using TLS from binding, then they are going to fail to bind once the changes are in effect. Now, does your ldapsearch command with -ZZ continue to work after there restart? What other processes have you configured to access the LDAP server from the local host? nscd? nss_ldap? etc. Look at those things. --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration

OS ( New server ) : RHEL AS 4 open ldap version ( on old server ) : 2.2.13-6.4E open ldap version ( on new server ) : 2.2.13-8.el4_6.4 please let me know if you need any conf information.

OpenLDAP on Windows XP possible?

I have an assignment to get OpenLDAP up and running on WindowsXP for a demo. The only thing I can find is a tar.gz which I unpacked, so now how do I get it installed on XP? I mostly see documentation for Unix/Linux systems but nothing as far as "Getting Started on XP" or anything windows related. thanks JavaTek

slapd hangs
by Curt Blank 21 Aug '08

21 Aug '08

Version 2.2.28 Periodically the slapd daemon hangs. I did a gstack (attached) which doesn't contain a lot of information but the one thing that stands out is at the top it says "Thread 18" and I have threads set to 16, is it somehow trying to create more then it is suppose to thus causing a problem? -- Curt Blank Systems Administrator Technical Services Specialist University Information Technology Services University of Wisconsin-Milwaukee e-mail: curt(a)uwm.edu phone : (414) 229-3814
