LDAP problem

Postby plagoutte » Thu Nov 21, 2019 7:58 pm


I involuntarily deleted the file data.mdb of LDAP and restarted Zimbra, hoping it will fix my mistake. But now, noting works...

Code: Select all

zimbra@phlag:~$ zmcontrol start

If I understand right, Zimbra restored the file thanks to its cache, but the passwords doesn't match anymore... This is what I tried :

./install.sh -s
./install.sh => not working (cf below)
Check the passwords in the config and change the LDAP root password with zmldappasswd -r

Infos :

Error chen trying to upgrade :

Code: Select all

ZCS upgrade from 8.8.15 to 8.8.15 will be performed.
Validating ldap configuration
Error: Unable to bind to the LDAP server as the zimbra LDAP user.
     This is required to upgrade.

I used the command "zmlocalconfig -s | grep ldap | grep pass" to show the current passwords : they all are equals, after modifying the LDAP root password with zmldappasswd

LDAP test :

Code: Select all

zimbra@phlag:~$ ldapsearch -LLL -h localhost -p 389 -D uid=zimbra,cn=admins,cn=zimbra -W
Enter LDAP Password:
ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)

I really hope someone can help me to repair my fault...
I use Zimbra 8.8.15 patch 4

Sorry for my English level, I'm French

What you aree seeing is the service startup procedure. When starting/restarting, the zmcontrol procedure asks the ldap for what services are installed and enabled on that server and what have to be started. If ldap is unreachable, zmcontrol tries to search them in HIS cache.
Unfortunately if you have wiped your mdb and don't have any sort of backup (ldap replicas, slapcat, zmbackup legacy, backup ng, third party backup systems...) , your ldap will not start and not only your user's password, but all your attributes are lost.
Trying to reinstall only software doesn't repair the damage, neither changing the ldap passwords.
