(ITS#7785) ContextCSN not updated
by badguy9588＠hotmail.com 13 Jan '14

13 Jan '14

Full_Name: Version: 2.4.11 OS: Redhat Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (202.82.28.193) We are using 4 ways multimaster openldap 2.4.11 for more than 5 years. On Jan 3, 2014, one of the openldap contextCSN is not updated, always stay at Jan 3 01:xx:xx, all the other servers are already updated to Jan 6. So, this introduce large amount of sync data between the 4 openldap servers finally, cause the slapd process memory increase from 500mb to 4Gb and finally, all memory used up and all 4 servers hanged and error message in KVM shows "Kernel panic, out of memory". The servers needed to reboot in order to resume access. However, after some time, it will happen again. We finally find that the contextCSN in one server is not updated. What we do is stop the slapd process in that server, delete the data files and the do a backup in other 3 servers. Then restore the backup in the problem server from the backup using slapadd and finally, all the data is synced. What's the root cause of this problem ? We have been using it for over 5 years already and this is the first time that this problem occurs. Thanks

Full_Name: Yo Lau Version: 2.3.32 OS: SUSE Linux Enterprise Server 10 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (12.130.146.228) When nss_ldap uses LDAP authentication with binding method, the bindpw stored in ldap.conf is clear text. However on Solaris NS_LDAP_BINDPASSWD could be stored in encrypted string. There is no password obfuscation with nss_ldap. So we considered it is a security issue and will affect the result of security audit.

Thanks for the report. This is now fixed in git master, plus another potential instance of the same issue.

(ITS#7783) tlsm_ctx_free crashes if ctx->tc_pin_file is null
by chris.w.martin＠oracle.com 10 Jan '14

Full_Name: Chris Martin Version: 2.4.23-32.el6_4.1 but also present in git repository version OS: Oracle Linux 6 URL: Submission from: (NULL) (148.87.19.206) If tlsm_ctx_free is entered with ctx->tc_pin_file null it will crash when it calls PL_strfree with that null pointer. http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=blob;f=libraries/… 2039 static void 2040 tlsm_ctx_free ( tls_ctx *ctx ) 2041 { ... 2069 PL_strfree( c->tc_pin_file ) I propose that an "if ( c->tc_pin_file )" be added before this line to protect against this. The specific use case when we hit this involves automount calling openldap ldap_start_tls_s which fails with LDAP_CONNECT_ERROR. automount then calls openldap ldap_unbind_ext which calls ldap_ld_free which calls ldap_int_tls_destroy which triggers this crash above.

Whatever Debian considers "stable" (for what definition?) is not relevant for OpenLDAP. Personally I consider the Debian packages rather unmaintained. Ciao, Michael.

>Why do you report issues for a release which is almost two years old without trying to reproduce it with a current release before? This is the actual openldap version distributed with the actual debian stable version (wheezy). I just made a full dist-upgrade and run into this problem. This thread is still active. So... Harry
