Full_Name: Martin Konold Version: 2.4.15 OS: Linux URL: http://www.erfrakon.de/konold/openldap-2.4.15.empty-db-segfault.patch Submission from: (NULL) (91.46.180.44) Previous versions of OpenLDAP could show a sig11 when doing slapcat (using bdb backend). The version 2.4.15 improved in this respect already though doing a slapcat with an emtpy db still results in a segmentation fault. The following small patch by andreas.mack at erfrakon.de resolves this issue http://www.erfrakon.de/konold/openldap-2.4.15.empty-db-segfault.patch The patch is used by the Kolab Project in productive installations Regards, -- martin

Re: (ITS#5983) ldappasswd returns "Additional info: password hash failed" in Solaris 10 SPARC
by mariusp44＠gmail.com 09 Mar '09

09 Mar '09

so I finally found what's the problem. I run openldap in chroot. In Solaris, function lutil_entropy() uses /dev/urandom (if configure script finds it which is my case) to generate random strings for salt. Since in chroot it was not able to open /dev/urandom since it was not existent in chroot jail and there is no any error message loged in the lutil_entropy() when open() returns value <0. it simply returns up to calling function. Once I mknod dev/urandom in chroot everything started to work properly. So it is definately not the bug nor is it compiler flaw. Not sure if it's required by coding standards but I would log some informative message if function fails to open a device apart from very generic "implementation specific" message.

ldapsearch weird results - wild card not working as expected
by Simon McGregor 09 Mar '09

09 Mar '09

I wrote a script to add groups to my ldap directory --------------------------------- #!/bin/sh # Get the latest gid gidlast="`ldapsearch -x "cn=*" -b "ou=Group,dc=mydomain,dc=com" -h myserver | grep gidNumber | awk '{ print $2 }' | sort -u | tail -n 1`" newgid="`echo "$gidlast + 1" | bc`" echo "newgid: $newgid" # Make the Mods echo "dn: cn=$1,ou=Group,dc=mydomain,dc=com" > /tmp/modify.ldap echo "changetype: add" >> /tmp/modify.ldap echo "objectClass: posixGroup" >> /tmp/modify.ldap echo "objectClass: top" >> /tmp/modify.ldap echo "cn: $1" >> /tmp/modify.ldap echo "gidNumber: $newgid" >> /tmp/modify.ldap # Run the Update ldapmodify -x -f /tmp/modify.ldap -h myserver -D cn=Manager,dc=mydomain,dc=com -w mypasswd ---------------------------------- This correctly creates a new group eg. ./mkgroup.sh mygroup01 $ ldapsearch -x "cn=mygroup01" -h myserver produces -> # mygroup01, Group, mydomain.com dn: cn=mygroup01,ou=Group,dc=mydomain,dc=com objectClass: posixGroup objectClass: top cn: mygroup01 gidNumber: 7435 memberUid: dummyuser The issue is the following: $ ldapsearch -x "cn=mygroup*" -b "ou=Group,dc=mydomain,dc=com" -h myserver | grep gidNumber | awk '{ print $2 }' | sort -u | tail -n 1 returns the result 7435 $ ldapsearch -x "cn=*" -b "ou=Group,dc=mydomain,dc=com" -h myserver | grep gidNumber | awk '{ print $2 }' | sort -u | tail -n 1 returns the result 7434 In other words the wild card is not picking up the new group even though it is actually there. Perhaps someone can show me the error of my ways but I think both results should return the same value I am running centos 5 with openldap-clients-2.3.27-8.el5_2.4 openldap-servers-2.3.27-8.el5_2.4 openldap-2.3.27-8.el5_2.4 openldap-devel-2.3.27-8.el5_2.4 The information contained in this email and any attachments is strictly confidential.
