[rudder-users] LDAP issue

Hello Matthieu,

Unfortunately it doesn't change anything.

[root at SERVER ldap]# tail -f slapd.log

Hi Cédric,

It seems the disk full condition happened just during a write operation in slapd, causing a corruption of it's BDB databases.

Let's fix it:

  *   First, you need the Berkeley DB utilities: yum install db4-utils
  *   Then, you need to make sure slapd is off: /etc/init.d/slapd stop
  *   Try to recover the databases: db_recover -h /var/rudder/ldap/openldap-data
  *   Reindex the database: /etc/init.d/slapd reindex
  *   Restart slapd: /etc/init.d/slapd start
  *   Take a look at the logs to see if the error happens again while using the webapp

Can you tell me if it solves the issue ?

Thanks in advance,

Hi François ,

Current Slapd.log and ldapsearch seems normal.

But I found that information in slapd.log-20140303 :
