Dear list,
We are using an OpenLDAP/slapd server to manage the user accounts of our Samba server and have recently run into the problem that users cannot connect to Samba drives anymore after some time. Samba complains that it cannot connect to the LDAP server (see below for error message in Samba log) and the slapd log shows

Mar 25 11:38:15 office-server slapd[3433]: bdb(dc=foo,dc=org): file id2entry.bdb has LSN 1/382892, past end of log at 1/283666

Strangely, restarting slapd helps and users can use Samba again for a limited and arbitrary period of time until the problem pops up again. I tried fixing the database using
db4.7_recover -v -h /var/lib/ldap
but again, the problem pops up again later.

For some unknown reason the last transaction logfile has been removed, therefor the database connot be recovered. Unfortunately you have to rebuild the database

Dieter,
First of all, thanks for your prompt and helpful reply!
I have just rebuild the database and will check now whether that did it.
For the sake of completeness (for others with similar problems), here's how I rebuilt the db:
/etc/init.d/slapd stop slapcat -l slapd-export.ldif -f /etc/ldap/slapd.conf -b "dc=foo,dc=org" rm -fr /var/lib/ldap/ # make sure this IS the path to your db as specified in slapd.conf mkdir /var/lib/ldap/ chgrp -R openldap /var/lib/ldap/; chown -R openldap /var/lib/ldap/ /etc/init.d/slapd start # creates an empty db /etc/init.d/slapd stop slapadd -l slapd-export.ldif -f /etc/ldap/slapd.conf -b "dc=foo,dc=org" chgrp -R openldap /var/lib/ldap/; chown -R openldap /var/lib/ldap/ /etc/init.d/slapd start
Best, Kaspar
