I'm going to change some schema and data in my ldap ;)
But 1st thing is how to restore ldap from ldiff file when something will go bad ...
1st is backup
2nd is store backup on other host/disk/whatever, it can be printed each time ;)
3rd is how to restore it when disaster come true ...
1st) backup like this? hm ... put it to cron ;)
[root@samba64 tmp]# slapcat -o ldif-wrap=no > slapcat-o-ldif-wrap-n.ldiff
2nd) when file is created send it somewhere ;)
3rd) restore from ldiff file, please remember about correct schema files,
if there is something 'strange' (my setup has some tweaks for Postfix) then also backup schema files :P just in case :P ;-)
how to restore it?
- shut down ldap server,
- remove broken files, in my case just clean directory /var/lib/openldap-data or rename it,
- change directory to /var/lib/openldap-data,
- do command: slapadd -v -l ~/LDAP/slapcat-o-ldif-wrap-n.ldiff,
- chown slapd:slapd files in /var/lib/openldap-data (beware, it is my PLD Linux ;) ),
- start ldap,
- check it. something like this:
ldapsearch -b "ou=Users,dc=XXXX,dc=pl" -D "cn=Manager,dc=XXXX,dc=pl" \
-w MyPassword -x -v \
-h 127.0.0.1\
'(&(objectClass=PostfixUser)(accountStatus=active))' mail
Uff done ...
Restore procedure looks like "IT WORKS!"
:-)
Next step is add and change some data in my secret schema ;) then do some tricks with ldiff file ...
