Right now, cmusaslsecretOTP is hardcoded, because if the shadow copy is used, OTP breaks. If it is acceptable to have it broken, we can remove the hardcoding, and let admins decide whether they prefer fail-over over consistency. I'd have no doubt, and favor consistency. p.

(ITS#6490) dds and pcache overlays not checking NULL value
by etienne.bagnoud＠irovision.ch 10 Mar '10

10 Mar '10

Full_Name: Etienne Bagnoud Version: 2.4.11 and HEAD OS: Debian GNU/Linux 5.0.4 URL: http://www.tchetch.net/code/openldap/ Submission from: (NULL) (153.109.35.2) When sending a refresh request (RFC 2589) with an empty DN, the server segfault. This did work on default Debian installed version (slapd 2.4.11) as well as on the actual (today) version in HEAD. The actual return value returned by 'select_backend' is not checked for NULL value and passed directly to 'SLAP_DYNAMIC' macro. While digging through the code to find how others overlays where doing, if found that pcache has the same behavior. I can't test for that overlay (if the bug is corrected or not), but I suppose it's the same. So here are two patches to correct dds overlay and pcache overlay : - http://www.tchetch.net/code/openldap/servers-slapd-overlays-dds.patch - http://www.tchetch.net/code/openldap/servers-slapd-overlays-pcache.patch I'm not used to dig into openldap code (in fact, this is the first time), so I hope it's ok.

(ITS#6489) Incomplete Master/Slave Replication
by Frank.Offermanns＠caseris.de 09 Mar '10

09 Mar '10

Full_Name: Frank Offermanns Version: 2.4.21 OS: Windwos URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (217.6.189.242) I am running LDAP from Head with BDB 4.8.26 as backend on windows. I am testing master/slave replication while adding 10000 users with 10 filled attributes. I am not using a specific time synchronization. Standard windows time synchronization in domains is active. But as far as I understood, a microsecond time synchronisation is only needed for master-master, which I am not testing. My problem is, that not every user and/or every attribute is replicated from my master to my slave. If the replicationmode is refreshAndPersist more entries are incorrect on the slave. When doing refreshOnly (every 5 mins) fewer entries have this problem. Switching to delta-syncrepl changes this behaviour. With delta-syncrepl once the intial content load has run, the replication seems to work 100%. But when I add entries while the inital content load (empty slave database) is running, a few complete users are missing (seems to be always a few in a row). But every written user has all attributes, so no missing attributes in this case. I will post my configuration (for refreshAndPersist replication). If you need any other info please let me known. Here my configurations: Master: ucdata-path ./ucdata include ./schema/core.schema include ./schema/cosine.schema include ./schema/Personcaesar.schema include ./schema/ConfigObjects.schema loglevel 0 pidfile ./run/slapd.pid argsfile ./run/slapd.args access to * by dn.one="ou=Admins,o=caesar" write by * read ####################################################################### # BDB database definitions ####################################################################### database hdb cachesize 10000 idlcachesize 30000 suffix "" checkpoint 1024 5 rootdn "cn=Administrator,o=caesar" rootpw {SHA}secret... directory "c:/all2421/data" dbconfig set_cachesize 0 400000000 1 dbconfig set_flags DB_LOG_AUTOREMOVE dbconfig set_lg_regionmax 1048576 dbconfig set_lg_max 10485760 dbconfig set_lg_bsize 2097152 # Indices to maintain index sn pres,eq index cn pres,eq,sub index MasterApp pres,eq index RightVoice pres,eq index DCOMServer pres,eq index ExtensionSMS pres,eq index ExtensionFax pres,eq,sub index ExtensionVoice pres,eq,sub index ExtensionCTI pres,eq index Deleted pres,eq index GUID pres,eq index CTIServerName pres,eq,sub index LastSyncUser pres,eq index ApplicationPhoneNr pres,eq,sub index NetDialLoginName pres,eq index email pres,eq index FullExtensionVoice pres,eq,sub index FullExtensionFax pres,eq,sub index FullExtensionSMS pres,eq index FullName pres,eq index PersonalID pres,eq index entryUUID eq index entryCSN eq index objectClass eq overlay syncprov syncprov-checkpoint 1000 60 syncprov-sessionlog 10000 ________________________________________________ Slave: ucdata-path ./ucdata include ./schema/core.schema include ./schema/cosine.schema include ./schema/Personcaesar.schema include ./schema/ConfigObjects.schema loglevel 0 pidfile ./run/slapd.pid argsfile ./run/slapd.args access to * by dn.one="ou=Admins,o=caesar" write by * read ####################################################################### # BDB database definitions ####################################################################### database hdb cachesize 10000 idlcachesize 30000 suffix "" checkpoint 1024 5 rootdn "cn=Administrator,o=caesar" rootpw {SHA}secret.... directory "c:/all2421_48/data" dbconfig set_cachesize 0 400000000 1 dbconfig set_flags DB_LOG_AUTOREMOVE dbconfig set_lg_regionmax 1048576 dbconfig set_lg_max 10485760 dbconfig set_lg_bsize 2097152 # Indices to maintain index sn pres,eq index cn pres,eq,sub index MasterApp pres,eq index RightVoice pres,eq index DCOMServer pres,eq index ExtensionSMS pres,eq index ExtensionFax pres,eq,sub index ExtensionVoice pres,eq,sub index ExtensionCTI pres,eq index Deleted pres,eq index GUID pres,eq index CTIServerName pres,eq,sub index LastSyncUser pres,eq index ApplicationPhoneNr pres,eq,sub index NetDialLoginName pres,eq index email pres,eq index FullExtensionVoice pres,eq,sub index FullExtensionFax pres,eq,sub index FullExtensionSMS pres,eq index FullName pres,eq index PersonalID pres,eq index entryUUID eq index entryCSN eq index objectClass eq syncrepl rid=001 provider="ldap://CAS-WS091201.domain.local" searchbase="o=caesar" type=refreshAndPersist retry="5 3 15 +" binddn="cn=Administrator,o=caesar" bindmethod=simple credentials="secret" sizelimit size.soft=100 size.hard=1000 size.prtotal=unlimited limits dn.exact="cn=Administrator,o=caesar" time.soft=unlimited time.hard=unlimited size.soft=unlimited size.hard=unlimited

After some chatter on the mailing list, the problem is now understood: - TLS error messages are indeed reported by OpenLDAP: TLS: could not use key file `/usr/local/etc/openldap/certs/ldap.key.pem'. TLS: error:0200100D:system library:fopen:Permission denied /usr/src/secure/lib/libcrypto/../../../crypto/openssl/crypto/bio/bss_file.c:356 TLS: error:20074002:BIO routines:FILE_CTRL:system lib /usr/src/secure/lib/libcrypto/../../../crypto/openssl/crypto/bio/bss_file.c:358 TLS: error:140B0002:SSL routines:SSL_CTX_use_PrivateKey_file:system lib /usr/src/secure/lib/libssl/../../../crypto/openssl/ssl/ssl_rsa.c:648 - The only way to see these error messages is to start the daemon with '-d stats' -- Setting 'loglevel stats' in slapd.conf will not cause these error messages to be printed. They only appear if the daemon is started in foreground mode with '-d stats'. My suggestions: print the TLS error messages out to syslog, or if that's not possible, print them to stdout regardless of whether the daemon is running in the foreground or not.

(ITS#6488) Nssov updates for new versions of nss-pam-ldapd
by crispy＠cluenet.org 06 Mar '10

06 Mar '10

Full_Name: Chris Breneman Version: 2.4.21 OS: Debian Lenny URL: http://scalar.cluenet.org/~crispy/nssov-nsspamldapd-update.patch Submission from: (NULL) (98.212.227.43) The nssov overlay currently includes a very old version of the nss-ldapd (now nss-pam-ldapd) source. It's not necessary to keep a source tree of nss-pam-ldapd within openldap now, as the patches for pam_ldap support in the stub library were integrated upstream. This patch removes the nss-ldapd source tree from nssov, except for a few files which are unlikely to change, and on which nssov depends. This patch also updates nssov to support the newer versions of nss-pam-ldapd. There were some organizational changes, header changes, and changes of the names of constants since the version of nss-ldapd that is currently in the source. This patch also removes the dependence on the configure script of nss-ldapd. Currently, the configure script has to be run in the nss-ldapd subdirectory to generate a few constants which are needed by the parts of nss-ldapd that nssov depends on. These same constants are generated by the openldap configure script, and this patch changes the include path to include the relevant header from the openldap configure script, instead of requiring a separate configure script from nss-ldapd. This patch also updates the nssov Makefile to use the new nss-pam-ldapd files location and to create an install target that is separate from the all target. The README and man page are updated to reflect that nss-ldapd is no longer included in the source, and point to where to get it. They are also changed to reflect the new name of nss-ldapd: nss-pam-ldapd The patch is at: http://scalar.cluenet.org/~crispy/nssov-nsspamldapd-update.patch It applies on the nssov directory.
