Problem with "force user to password reset at first login
by Rajagopal Rc 30 Oct '23

30 Oct '23

Hi, I am trying to force users to change their password at first login or after password reset by administrator. Tried following: 1)Password policy 'pwdMustChange TRUE' doesn't seems to be working as non of the users get prompt to change their password at first login. 2) used the 'pwdReset TRUE' attribute in users attributes, and it won't prompt to change the password and didn't allow to login i observe below messages in log "slapd[12684]: connection restricted to password changing only slapd[12684]: send_ldap_result: err=50 matched="" text="Operations are restricted to bind/unbind/abandon/StartTLS/modify password" slapd[12684]: conn=1053 op=1 SEARCH RESULT tag=101 err=50 nentries=0 text=Operations are restricted to bind/unbind/abandon/StartTLS/modify password" Please help me configure the option to force all users to change their password at first login or after pwd reset by administrator.

slapd-meta
by Fr3ddie 07 Nov '16

07 Nov '16

Hello to the list, I'm trying to configure the slapd-meta OpenLDAP backend on an online cn=config configuration with no luck. Slapd version is 2.4.39 (the maximum I can achieve on the target machines building from vanilla source). The documentation is clear but too concise for me so I will try to explain what I'm trying to do to see if there is anybody that can help me. Currently I have 3 slapd servers that share a common root for the DIT, i.e.: dc=loc1,dc=root dc=loc2,dc=root dc=loc3,dc=root What I would like to achieve is to obtain a fourth server that contains the previous trees, along with its own tree, i.e. a server that contains: dc=loc0,dc=root (locally hosted data) dc=loc1,dc=root (coming from the first server, chasing referrals) dc=loc2,dc=root (coming from the second server, chasing referrals) dc=loc3,dc=root (coming from the third server, chasing referrals) this way, all the clients connecting to this server will be able to retrieve data also from the other three remote servers. As far as I understood, I only need to configure the "loc0" server to access the other three servers and get the data to serve to clients. I have already configured the fourth server with its local DIT and this is the configuration: # cat 'cn=config.ldif' dn: cn=config objectClass: olcGlobal cn: config olcArgsFile: /var/run/slapd/slapd.args olcPidFile: /var/run/slapd/slapd.pid structuralObjectClass: olcGlobal creatorsName: cn=config olcServerID: 1 olcThreads: 32 olcToolThreads: 8 olcRequires: LDAPv3 olcConnMaxPendingAuth: 100 olcTLSCACertificateFile: /etc/ssl/certs/my_ca_cert.pem olcTLSCertificateFile: /etc/ssl/certs/this-host_x509_cert.pem olcTLSCertificateKeyFile: /etc/ssl/private/this-host_x509_key.key olcTLSVerifyClient: try olcTimeLimit: 600 olcLogLevel: stats2 sync [...] # cat 'cn=module{0}.ldif' dn: cn=module{0} objectClass: olcModuleList cn: module{0} olcModulePath: /usr/lib/ldap olcModuleLoad: {0}back_hdb olcModuleLoad: {1}syncprov olcModuleLoad: {2}accesslog structuralObjectClass: olcModuleList [...] Schema files are the following: cn={0}core.ldif cn={1}cosine.ldif cn={2}nis.ldif cn={3}inetorgperson.ldif cn={4}dyngroup.ldif cn={5}kerberos.ldif # cat 'olcDatabase={1}hdb.ldif' dn: olcDatabase={1}hdb objectClass: olcDatabaseConfig objectClass: olcHdbConfig olcDatabase: {1}hdb olcDbDirectory: /var/lib/ldap olcSuffix: dc=loc0,dc=root olcAccess: {0}to attrs=userPassword,shadowLastChange,krbPrincipalKey by dn="cn =admin,dc=loc0,dc=root" write by anonymous auth by self write by * none olcAccess: {1}to dn.base="" by * read olcAccess: {2}to * by dn="cn=admin,dc=loc0,dc=root" write by * read olcLastMod: TRUE olcRootDN: cn=admin,dc=loc0,dc=root olcRootPW:: xxxxxxxxxxxxxxxxxxxx olcDbCacheSize: 10000 olcDbCheckpoint: 512 10 olcDbConfig: {0}set_cachesize 0 524288000 1 olcDbConfig: {1}set_lk_max_objects 1500 olcDbConfig: {2}set_lk_max_locks 1500 olcDbConfig: {3}set_lk_max_lockers 1500 olcDbConfig: {4}set_flags DB_LOG_AUTOREMOVE olcDbIDLcacheSize: 30000 olcDbIndex: default pres,eq [...] structuralObjectClass: olcHdbConfig olcSyncrepl: {0}rid=0 provider=ldap://second-host.loc0.root bindmethod=s imple binddn="cn=admin,dc=loc0,dc=root" credentials=xxxxxx searchbase="dc=loc0,dc=root" logbase="cn=accesslog" logfilter="(&(objectClass=auditWriteObj ect)(reqResult=0))" schemachecking=on type=refreshAndPersist retry="60 +" syn cdata=accesslog starttls=yes olcMirrorMode: TRUE [...] On top of this DB I have the "syncprov" and the "accesslog" overlays configured (these are two servers in "MirrorMode", configured following the OpenLDAP admin documentation).

At this point I'm stuck to this error and I wasn't able to find any hint on the web to solve this :( The examples I was able to find were related with the static slapd.conf configuration, I counldn't find any "full" configuration example using the cn=config. I'm wondering if I should create a "cn=root" actual DB first and then link the sub-DITs to it, or, maybe, add some other overlay... I really can't understand how it should work :( Can please anybody help me? Thank you very much

Virtual list view problem

Hi all I am using cpan Net::LDAP module to access LDAP entries. I want to search LDAP entries using Net::LDAP search method. When I do search, I want some limited number of entries from search result, for this(searching) process I am using Net::LDAP::Control::VLV module. But I get error on VLV response control. Please, any one have idea about this error. * Error:* Died at vlv.pl line 50, This is my example.

storing HA1 password hash for HTTP DIGEST, SIP, TURN
by Daniel Pocock 06 Mar '16

06 Mar '16

Hi all, There are a few protocols that use a HA1[1] password hash, such as HTTP DIGEST[1], SIP DIGEST[2] and TURN[3] (which uses HMAC rather than DIGEST) Is there a standard LDAP attribute name for storing a HA1 value or should it be stored in a regular userPassword attribute as described in the manual[4]? I came across smbk5pwd for keeping SMB password attributes in sync. Is there a similar facility for keeping HA1 passwords in sync when a user changes the password or how could a developer go about adding that, would the smbk5pwd source be a useful model? Regards, Daniel 1. http://tools.ietf.org/html/rfc2617#section-3 2. https://tools.ietf.org/html/rfc3261#section-22.4 3. https://tools.ietf.org/html/rfc5389#section-15.4 4. http://www.openldap.org/doc/admin24/security.html#Password%20Storage

chaining for a single backend?
by Marc Patermann 11 Feb '16

11 Feb '16

Hi, I want to activate chaining for a single backend. The server is a replication consumer and has a few glued database backends. Only one is containing linux accounts with ppolicy overlay. This should use chaining to replicate the ppolicy changes which otherwise stay local. Can this be achieved? Marc

LMBD questions (stat & copy)
by Bruno Freudensprung 14 Jan '16

14 Jan '16

Hi, I am trying to detect MDB_MAP_FULL based on mdb_stat(txn, dbi, &stat) results and I am wondering if I am on the right track or doing things correctly. I have a small and simple test program (http://pastebin.com/SPCYgWMC) exhibiting the following behavior (consistent between Windows 7 64-bit and Ubuntu 15.10 64-bit - latest version of lmdb cloned and recompiled on Linux): * Inserting 20990 key value pairs in a database is OK when using one transaction. Just before commiting the write transaction, mdb_stat(txn, dbi, &stat) shows that the total number of pages (253) is very close the the number of pages of the map (256). Indeed, adding another entry leads to MDB_MAP_FULL. To put it shortly, this scenario looks OK (I am assuming there might be 3 "internal-purpose" pages not shown by mdb_stat) and can be tested by setting the stat_test variable to 0 at line 20 of the test program. * Inserting same 20990 key value pairs in a database fails (MDB_MAP_FULL encountered at 19357) when using two consecutive write transactions. Just before MDB_MAP_FULL, mdb_stat(txn, dbi, &stat) shows that the total number of pages (232) is "quite far" from the the number of pages of the map (256), leading my MDB_MAP_FULL detection heuristic to fail. It means that only 92% of the total amount of data can be sucessfully added to the database. Other scenarii (with same key/value lengths though) stop at 85% only. This can be tested by setting the stat_test variable to 1 (line 20). By "total number of pages" I mean ms_branch_pages + ms_leaf_pages + ms_overflow_pages. Do you think I am on a wrong track? (maybe mdb_stat does not show 24 "internal-purpose" pages in the second case? or I am forgetting something?). One last remark: it seems that mdb_env_copy(db, copy_dir) is possible during a write transaction on Windows (like stated in the documentation), but not on Linux (the test program seems to be stopped on a mutex at line 62). This can be tested by changing the copy_test variable to 1 at line 19. Is it expected given my program? Best regards, Bruno.

Aaargh, now I can't help thinking about "providers" whipping "replicas". slapd can be so cruel sometimes :-) And in case you wonder, here in reunion island we have a (relatively) long history of slavery.

If you are replicating > cn=config across all the systems, then they must all be masters. Your > general description above sounds like you do not correctly understand how > MMR functions. OK... I finally understand what was bothering you My replicas do _not_ accept writes. Sorry to have let you think so I have two setups: - a "legacy" one, with one master accessible to the applications that can write, and two complete replicas (data + cn=config) behind a loadbalancer for the reads. One of these replicas could become the new master if the needs arise. And there are a bunch of partial replicas (only a subset of data) for some specific services. The reason is on our vmware farm, network access is regularly cut (don't know why, the system guy neither), and these services cannot reconnect on their own... piece of #$*! software :( - a "new" one, with two masters in mirror mode (only one get the writes at anytime thanks to the loadbalancer), and two replicas (only data) which get all the reads. I feel like configuring chaining to be able to write from the replicas, but I have no experience of the benefits of this configuration... I have read the admin guide several times, but I am open to any suggestion to improve my skills > >>> Accesslog is unique to a given master. >> >> Ok that's what I wanted to know for sure >> >> Shouldn't the doc stat this clearly? > > > Please file an ITS noting the docs should be updated on this point.

LMDB ITS 8324 WriteMap performance on Windows
by Victor Baybekov 05 Jan '16

05 Jan '16

Hi, Thanks a lot for ITS#8324! For embedded, not server, use case that change adds much convenience. I have tested the master from .NET via P/Invoke and do not see any major slowdown with default options. To insert 10M <int32,int32> pairs inside a single transaction v.0.9.14 takes minimum 3400 msec, latest master takes minimum 3750 msec. This is not scientific, just best result from 10 runs. Sometimes both timings increase to 5000+ msecs. On average slowdown is visible but tolerable - from 2.9 Mops to 2.6 Mops (absolute numbers are still awesome!). With Append and NoSync I could get 3.45 Mops on the same test with master build. However, with WriteMap performance of master drops 3x to 10000 msec or just 1 Mops, while for the v.0.9.14 performance with WriteMap improves to 2350 msec or 4.25 Mops. Is this the cost of convenience or it could be fixed so that WriteMap still "is faster and uses fewer mallocs" as the docs say? Best regards, Victor
