ppolicy and ACLs of pwdAccountLockedTime?
by chantra 06 Sep '09

06 Sep '09

Hi all, I have exactly the same issue. My repro config is within the .tgz attached to this email. admin user is cn=admin,dc=example,dc=com and test user is uid=chantra,ou=users,dc=example,dc=com password for both of them is "foobarcode". To reproduce, on Debian Lenny, * untar the archive * cd ldaps * ./install.sh (WARNING: ONLY DO THIS ON A TEST MACHINE, current setup/db will be ERASED). That will stop slapd, override the config with the repro config, erase the current database, inject the testing one with slapadd, give credential to /var/lib/ldap to openldap user, start slapd Then, run: for i in {1..10}; do ./ldapauth.sh $i; sleep 2; done; ./ldaps.sh which will perform 10 failed authentication, with a pause of 2 seconds. Finally, ldaps.sh will output the details of user uid=chantra,ou=users,dc=example,dc=com @Jiri, have you found a solution yet? In my repro, here is the result after the 10 failed auth: # chantra, users, example.com dn: uid=chantra,ou=users,dc=example,dc=com structuralObjectClass: inetOrgPerson entryUUID: 2e93af32-2d8d-102e-8fab-21ae2aafa5d0 creatorsName: createTimestamp: 20090904105519Z entryCSN: 20090904105519.875933Z#000000#000#000000 modifiersName: modifyTimestamp: 20090904105519Z pwdFailureTime: 20090904105614Z pwdFailureTime: 20090904105616Z pwdFailureTime: 20090904105618Z pwdFailureTime: 20090904105620Z entryDN: uid=chantra,ou=users,dc=example,dc=com subschemaSubentry: cn=Subschema hasSubordinates: FALSE Again, here, we see only 4 pwdFailureTime (the 5th should have locked user ).

Michael mentioned to try 2.4.17 which as changes that might affect pwdLockout (actually, ITS#6168 was because users where locked out while pwdLockout was set to FALSE, AFAICS), to no avail Then, I tried the setting from the archive on Fedora11, and Debian Etch, same issue... There is surely something that I am missing here, but shouldn't pwdAccountLockedTime being handled by the daemon? no access rule should be set ( except the for the fact that the admin user can write/delete it). What rule am I missing here? If needed, I can provide a VMDK of the repro, let me know and I will upload it somewhere.

Bizzar Behaviour from openldap-2.4.16 on Centos

Hi, Forgive me if this is an obvious one, as i'm new to openldap.

perl module to read ldif
by William Bryan 05 Sep '09

05 Sep '09

I was once told that there is an add on to perl that would allow you to read an ldif just like it was a slapd directory. I guess that calls to ldapsearch get rerouted to search the ldif. Does anyone know the package and/or details. thank you

Creating Structural Objects Under User Records
by Tim Gustafson 03 Sep '09

03 Sep '09

I'd like to be able to create "sub-objects" inside each user object. So, my account is: uid=tjg,ou=People,dc=soe,dc=ucsc,dc=edu I'd like to be able to create an object like: cn=foo,uid=tjg,ou=People,dc=soe,dc=ucsc,dc=edu This object would be of objectClass "soeDegree", which I've defined as follows: attributetype ( 1.1.2.1.32 NAME 'soeDegreeYear' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE ) attributetype ( 1.1.2.1.33 NAME 'soeDegreeType' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE ) attributetype ( 1.1.2.1.34 NAME 'soeDegreeDepartment' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE ) attributetype ( 1.1.2.1.35 NAME 'soeDegreeThesisTitle' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE ) attributetype ( 1.1.2.1.36 NAME 'soeDegreeThesisURL' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE ) objectclass ( 1.1.2.1.997 NAME 'soeDegree' DESC 'Jack Baskin School of Engineering Degree' SUP top STRUCTURAL MUST ( cn ) MAY ( soeDegreeYear $ soeDegreeType $ soeDegreeDepartment $ soeDegreeThesisTitle $ soeDegreeThesisURL )) However, when I attempt to add the sub-object, the server returns: 0x35 (LDAP_UNWILLING_TO_PERFORM) How can I tell OpenLDAP to allow me to create child objects inside accounts like this?

syncrepl "modified by peer" question
by Robert Hanson 02 Sep '09

02 Sep '09

(verson 2.4.17) This code is in syncrepl.c /* Don't send changed entries back to the originator */ if ( sid == srs->sr_state.sid && srs->sr_state.numcsns ) { Debug( LDAP_DEBUG_SYNC, "Entry %s changed by peer, ignored\n", rs->sr_entry->e_name.bv_val, 0, 0 ); return LDAP_SUCCESS; Can someone explain to me what the intention of this code is? I can read the comment, but it looks to me like the condition for the if is broken. I think it is saying - if (the system id of the modification is "this system") and (there was a sync cookie found at startup) then discard the update The longer I look at this, the less I'm convinced that the condition check matches what the comment says it does. Any comments?

labeledURI search result objectClass restriction
by Torsten Rehn 02 Sep '09

02 Sep '09

Hi, it appears that a search triggered from a labeledURIObjects search URI can't have any results that are the same objectClass as the triggering object. I had one groupOfNames that was looking for other groups to be added as members. Debugging told me OpenLDAP came up with this when doing the internal search: put_filter: "(&(!(objectClass=groupOfNames))(objectClass=groupOfNames))" while I had of course specified only (objectClass=groupOfNames) as a filter. Can anyone please explain this behavior and/or provide a workaround? Thanks, -- Torsten Rehn

OpenLDAP client authentication against JDS 6.3.1 server
by Cannon, Andrew C 02 Sep '09

02 Sep '09

Dear list members, I've been fighting with this problem on and off for 6 months now (you can see some of my queries if you Google for me...) and I cannot for the life of me figure out what is going on. We are trying to get a Fedora 9 test box to authenticate against a Solaris 10 (SPARC) Sun Java Directory Server 6.3.1 box using anonymous binding and no SSL (we are on an internal, trusted network). The JDS is running the NIS-to-LDAP script that Sun provide and can get information from the directory. The Fedora box is running OpenLDAP client (version: openldap-clients-2.4.10-2.fc9.x86_64) and can't get any infromation from the directory after I switch to LDAP authentication from NIS authentication using system-config-authentication. NIS on the Fedora box works fine, so it isn't a network issue. An extract from the access log on the server shows the following: [01/Sep/2009:11:11:24 +0100] conn=2618 op=-1 msgId=-1 - fd=47 slot=47 LDAP connection from 172.28.1.172:46682 to 172.28.1.173 [01/Sep/2009:11:11:24 +0100] conn=2618 op=0 msgId=1 - BIND dn="" method=128 version=3 [01/Sep/2009:11:11:24 +0100] conn=2618 op=0 msgId=1 - RESULT err=0 tag=97 nentries=0 etime=0 dn="" [01/Sep/2009:11:11:24 +0100] conn=2618 op=1 msgId=2 - SRCH base="ou=people,dc=example,dc=com" scope=1 filter="(&(objectClass=posixAccount)(uid=dmm))" attrs="uid userPassword uidNumber gidNumber cn homeDirectory loginShell gecos description objectClass" [01/Sep/2009:11:11:24 +0100] conn=2618 op=1 msgId=2 - RESULT err=0 tag=101 nentries=0 etime=0 [01/Sep/2009:11:11:42 +0100] conn=2618 op=2 msgId=0 - RESULT err=80 tag=120 nentries=0 etime=0 [01/Sep/2009:11:11:42 +0100] conn=2618 op=-1 msgId=-1 - closing from 172.28.1.172:46682 - A1 - Client aborted connection - [01/Sep/2009:11:11:42 +0100] conn=2618 op=-1 msgId=-1 - closed.

I'm sorry for the newbie questions (especially about a JDS server) but I am really tearing my hair out over this. I hope some of you can help. Thanks in advance.

Sycrepl cookie question
by Robert Hanson 01 Sep '09

01 Sep '09

(2.4.17; linux, bdb 4.5 backend; two nodes in a multi-master configuration) When I start up a slapd server, it reads the contextCSN from the database. There are some synchronization issues I'm dealing with (see the email I sent yesterday to this group). The question of the day is, what are the implications if I delete this from the database before I start up? That is: Assume that in a 2-node multi-master scenario, both sides are completely in sync. One of the nodes goes down; assume that the remaining node gets some updates. The down node comes back up. If the down node does not have this synchronization cookie, will it still sync correctly with the other node?

PADL migration tools / NIS to LDAP
by Ivan De Masi 01 Sep '09

01 Sep '09

Hello, I'm fairly new to LDAP and testing for migration (NIS to LDAP). I found the PADL migration tools http://www.padl.com/OSS/MigrationTools.html which are great and now im testing the export of data-sources to *.ldif files. When exporting the passwd-file for example, I have all system-accounts like "daemon", "bin", "sys", etc. (let's say everything with the uid below 1000) in the ldif file. Do I need this all these accounts in LDAP? I see that there is "krbName" for all exported entrys/accounts. That's good for some services and kerberos, but do I really need *all* system accounts in LDAP? Thanks! Regards, Ivan

Slow LDAP
by sgmayo＠mail.bloomfield.k12.mo.us 01 Sep '09

Is there some way to speed up LDAP? I am guessing this has to do with it searching the database on ldap? This is a new server and my old one did not take that long. It is not as slow if just one or two people are logging in with ldap, but when many login, it seems to bring ldap to a bottle neck, I guess while searching the directory for all the names. There are probably about 1000 users in my LDAP. Is that too large? I assume it isn't since most of the other schools around have AD which is basically Microsoft LDAP if I understand correctly and they have no problems and have many more users than I have. Can multiple schema's in the config file cause this? I know that on my old server I had the following in slapd.conf: core cosine inetorgperson nis samba On my new one it has the above plus: corba duaconf dyngroup java misc openldap ppolicy collective Those were just in there when I installed it so I left them. Should I take them out or would that not have any affect on logins at all? I am guessing that they wont' affect anything and it is more related to some sort of configuration in my ldap configs. Is there something else I need in a config? Here are my configs. slapd.conf include /etc/openldap/schema/corba.schema include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/duaconf.schema include /etc/openldap/schema/dyngroup.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/java.schema include /etc/openldap/schema/misc.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/openldap.schema include /etc/openldap/schema/ppolicy.schema include /etc/openldap/schema/collective.schema include /etc/openldap/schema/samba.schema loglevel -1 sizelimit -1 allow bind_v2 pidfile /var/run/openldap/slapd.pid argsfile /var/run/openldap/slapd.args database bdb suffix "dc=school,dc=bloomfield.k12.mo.us" checkpoint 1024 15 rootdn "cn=Manager,dc=school,dc=bloomfield.k12.mo.us" rootpw ***** directory /var/lib/ldap index objectClass eq index cn,sn,uid,displayName eq,pres,sub index uidNumber,gidNumber eq index memberUid eq index sambaSID,sambaPrimaryGroupSID eq index sambaDomainName eq index default sub database monitor ldap.conf SIZELIMIT 200 HOST 127.0.0.1 10.0.0.5 BASE dc=school,dc=bloomfield.k12.mo.us I have a DB_CONFIG file that contains the following, but not sure if it needs anything else or not: set_cachesize 0 268435456 1 set_lg_regionmax 262144 set_lg_bsize 2097152 Thanks for any info. -- Scott Mayo - System Administrator Bloomfield Schools PH: 573-568-5669 FA: 573-568-4565 Question: Because it reverses the logical flow of conversation.
