Sounds like a nightmare of internal searches if we want to generate it on the fly (although possibly acceptable by those queries that require it). It might be worth to consider storing it in directory, and track add/rename operations accordingly. The overlay that implements it should also provide a tool hook for bi_tool_entry_put. p. Ing.

(ITS#6018) TLS memory leak
by timling2003＠gmail.com 12 Mar '09

12 Mar '09

Full_Name: Tim Ling Version: 2.3.32 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (202.111.48.66) I develop a client of LDAP with TLS/SSL. This client is a daemon to query LDAP server. For SSL, I use ldap_initialize(ld, "ldaps://..."). For TLS, I use ldap_start_tls_s( ld, NULL, NULL ). I also use ldap_set_option( ld, LDAP_OPT_PROTOCOL_VERSION, &protocol ) (protocol=3) and ldap_set_option( NULL, LDAP_OPT_X_TLS_REQUIRE_CERT, &rc ) (rc=0). The method of bind is LDAP_AUTH_SIMPLE. For every request, I will call ldap_initialize(). After that, I will use ldap_unbind_s(ld). ( I cannot use ldap_pvt_tls_destroy(), because this function can be called only once ). After handling a lot of requests, it will cause memory leak.

Well, I think we could also provide sort of an off-line means to check what is statically built-in and what's not. In principle, one could implement tool mode in back-monitor and perform a echo "database monitor" > slapd.conf slapcat -f slapd.conf -s "cn=Backends,cn=Monitor" | grep whatever slapcat -f slapd.conf -s "cn=Overlays,cn=Monitor" | grep whatever to find what's available. If it fails, back-monitor itself is needed; then echo "modulepath path/to/back-monitor" > slapd.conf echo "moduleload back_monitor.la" >> slapd.conf echo "database monitor" >> slapd.conf slapcat -f slapd.conf -s "cn=Backends,cn=Monitor" | grep whatever slapcat -f slapd.conf -s "cn=Overlays,cn=Monitor" | grep whatever Looks like an overkill, but it might be of general usefulness. p.

We'll change moduleload to check for already-existing backends or overlays, and silently succeed in those cases. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

I see quite a few issues (unless already discussed). For example, one would typically discover the need to load back_monitor.la only close to the end of the configuration, while the module defines some specific schema and even some specific calls that may be needed by other backends instantiated earlier in order to allow custom monitoring. I guess the problem can be generalized. > And before we go there, what if we just provided a slapd option to dump out > all of its compiled-in paths?

(ITS#6017) Implement parentGUID or similar in OpenLDAP
by abartlet＠samba.org 11 Mar '09

Full_Name: Andrew Bartlett Version: 2.4.15 OS: Fedora 9 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (59.167.251.137) Samba4 would find it most helpful if OpenLDAP would be able to present an operational attribute 'parentGUID' similar to the one that Windows 2008 has implemented in AD. http://msdn.microsoft.com/en-us/library/cc221277(PROT.13).aspx Formalised details of the required semantics are not very clear at this point (I will request clarification from Microsoft on this), but for now: The root entries on a partition have no parentGUID All other entries have a value parentGUID equal to the objectGUID of the parent This value is available in search results if requested. As Samba handles the translation from text to binary, feel free to use the existing entryUUID formatting. Implementing this would avoid Samba having to perform an auxillary search to find this information, which should be very cheaply available to hdb when it is resolving the DN. Thanks, Andrew Bartlett (Discussed with Howard Chu on #openldap-devel)
