server-side sub-search
by Benin Technologies 31 Jan '13

31 Jan '13

Hi, Is it possible to do a server-side sub-search before returning the data to the client ? Let's say I have this tree : ---> dc=com | |-->dc=mycompany | | --> cn=Jane Doe | |-- objectClass=inetOrgPerso |-- cn=Jane Doe |-- mobile : 11223344 | --> cn=secretary | |-- objectClass=organizationalRole |--cn=secretary |--telephoneNumber=12345678 |--roleOccupant=cn=Jane Doe,dc=mycompany,dc=com I'd like to return, in a single search, something like : cn : Jane Doe - mobile : 11223344 - telephoneNumber : 12345678 Can this be done ? Ben

Search speed regarding BDB_IDL_LOGN and order in search filter
by Meike Stone 31 Jan '13

31 Jan '13

Hello, I'm sorry, but I want to ask again for clarifying. First question: - An index slot is loosing precision if the search result for an (indexed) attribute is larger than 2^16. Then the search time is going to increase a lot. - I can change this via BDB_IDL_LOGN. - But if I have a directory, that holds 200.000 employees with '(ObjectClass=Employees)', the result is larger than 2^16 and it is slow. - lets say, the employees are distributed over 4 continents and the DIT is structured geographical eg.: o=myOrg, c=us (100,000 employees) o=myOrg, c=gb ( 30,000 employees) o=myOrg, c=de ( 25,000 employees) o=myOrg, c=br ( 45,000 employees) Can i prevent it this problem with index slot size, if I change the search base to "o=myOrg, c=gb", because there are only 30,000 employees. This takes me to the second question: "How is a search filter evaluated?" Lets say, I combine three filter via "and" like '(&(objectlass=Employees)(age=30)(sex=m))' and the all attributes are indexed. Each filter results: (objectlass=Employees) => 200,000 entries (age=30) => 10,000 entries (sex=m) => 3,000 entries Does the order matter regarding speed, is it better to form the filter like this? '(&(sex=m)(age=30)(objectlass=Employees))' Thanks Meike

CLOSE_WAIT TCP connection
by Vanpeer 31 Jan '13

31 Jan '13

Hello, Could you please help me to understand the problem that i didn't really resolv.. I have my openldap platform which has been working well OpenldapServer : 2.3.39 Openldapclient : RedHat 5.x with nss_ldap and pam_ldap.so release 253-51 All my servers were configured with : /etc/nsswitch.conf /etc/ldap.conf and /etc/pam.d/sshd The user authentification with ssh connection is perfect. The filter of authorisation host connection is ok too. Everything is ok. But i've recently realized that i have a lot of TCP CLOSE_WAIT connexion from differents servers to my OpenLdapServer. These connexions are somethings like : tcp 1 0 IP_CLIENT:44633 OPENLDAP_SERVER:389 CLOSE_WAIT 3321/crond off (0.00/0/0) tcp 1 0 IP_CLIENT:44674 OPENLDAP_SERVER:389 CLOSE_WAIT 2426/nagios off (0.00/0/0) tcp 1 0 IP_CLIENT:44956 OPENLDAP_SERVER:389 CLOSE_WAIT 4652/ntpd off (0.00/0/0) ..... And so on .. I have ~20 TCP CLOSE_WAIT connection to OPENLDAP_SERVER I don't understand when these applications tried to connect to OPENLDAP server and why i have TCP persistent connexion. Meanwhile, I only have SSHD configured to use pam_ldap.so ... Someone can help me please ?!? Thanks by advance for your answer and i m sorry about my English

ldapsearch question
by Benin Technologies 29 Jan '13

29 Jan '13

Hi, I was wondering if the following search can be done. Let's say I have this tree : ---> dc=com | |-->dc=mycompany | | -->cn=Jane Doe | |-- objectClass=inetOrgPerson |-- cn=Jane Doe |-- mobile : 11223344 |--> cn=secretary | |--objectClass=organizationalRole |--cn=secretary |--telephoneNumber = 12345678 I'd like to return, in a SINGLE search, something like : cn : Jane Doe - mobile : 11223344 - telephoneNumber : 12345678 In other words, I'd like the search to return the attribute telephoneNumber AS an attribute of Jane Doe, and not as an attribute of Jane Doe --> cn=secretary Ben

ldapsearch trying to use SASL
by Scott Classen 29 Jan '13

29 Jan '13

Hello, I have a script which checks for the existence of an email address in my LDAP directory. the relevant line is: ldapsearch -D "uid=nss,dc=bah,dc=com" -w mypassword -b "ou=People,dc=blah,dc=com" uid=bobthebuilder mail If I run this script as the root or tomcat user it works as expected and returns the mail attribute. If this script is called from Apache Tomcat webapp (running as the tomcat user). I receive the following errors in my slapd.log file: Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 fd=26 ACCEPT from IP=131.1.2.3:50230 (IP=0.0.0.0:389) Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=0 SRCH base="" scope=0 deref=0 filter="(objectClass=*)" Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=0 SRCH attr=supportedSASLMechanisms Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=0 SEARCH RESULT tag=101 err=0 nentries=1 text= Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=1 BIND dn="uid=nss,dc=bah,dc=com" method=163 Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=1 RESULT tag=97 err=14 text=SASL(0): successful result: security flags do not match required Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=2 BIND dn="uid=nss,dc=bah,dc=com" method=163 Jan 29 13:59:29 bl1 slapd[3783]: SASL [conn=247839] Failure: no secret in database Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 op=2 RESULT tag=97 err=49 text=SASL(-13): user not found: no secret in database Jan 29 13:59:29 bl1 slapd[3783]: conn=247839 fd=26 closed (connection lost) I don't understand why the ldapsearch is searching for attr=supportedSASLMechanisms when invoked from within a Tomcat Webapp, but works fine when invoked from a c shell. Any ideas? Your help is greatly appreciated. Scott
