Bug #10505
closed
During a migration from 4.0 to 4.1, ldap base was emptied
Description
I'm not exactly sure about what happened, I don't see error in the process, but after the upgrade, the LDAP base is completely empty (not even root object).
The first symptom was that there was no CSS/JS at all, which is strange and reminds #10430.
The webapp logs are full of LDAP errors:
[2017-03-24 14:51:26] ERROR com.normation.rudder.repository.ldap.LDAPGitRevisionProvider - The root entry of the user template library was not found, the current revision won't be persisted [2017-03-24 14:51:28] ERROR com.normation.ldap.sdk.ROPooledSimpleAuthConnectionProvider - Can't execute LDAP request com.unboundid.ldap.sdk.LDAPSearchException: no such object >-at com.unboundid.ldap.sdk.LDAPConnection.search(LDAPConnection.java:3650) ... [2017-03-24 14:51:28] ERROR com.normation.ldap.sdk.ROPooledSimpleAuthConnectionProvider - Can't execute LDAP request com.unboundid.ldap.sdk.LDAPSearchException: no such object >-at com.unboundid.ldap.sdk.LDAPConnection.search(LDAPConnection.java:3650)
An ldapsearch returned excatly nothing:
root@server:/var/rudder/ldap/backup# ldapsearch -v -h localhost -p 389 -x -D "cn=Manager,cn=rudder-configuration" -w b385ddd5a0b4 -b "cn=rudder-configuration" -s sub "1.1" ldap_initialize( ldap://localhost:389 ) filter: (objectclass=*) requesting: 1.1 # extended LDIF # # LDAPv3 # base <cn=rudder-configuration> with scope subtree # filter: (objectclass=*) # requesting: 1.1 # # search result search: 2 result: 32 No such object # numResponses: 1
So, this was easely solved by restauring the pre-migration backup, but it is not quite satisfying:
$ service rudder-slapd stop $ cd /var/rudder/ldap/backup $ gunzip openldap-data-pre-upgrade-20170324143846.ldif.gz $ /opt/rudder/sbin/slapadd -l openldap-data-pre-upgrade-20170324143846.ldif $ /etc/init.d/rudder-slapd start $ service rudder-jetty restart

I can trigger it if during a migration, I'm replying "Y" to the conf file update of slapd:
Configuration file '/opt/rudder/etc/openldap/slapd.conf'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** slapd.conf (Y/I/N/O/D/Z) [default=N] ?
But I wasn't able to reproduce it in the normal, documented update process.

The reason is that if we choose to get the new config file version, not database migration is triggered, and Ragnarök ensues.

Since #10517, the migration is done EVEN if the user didn't read the document and answered [Y] to use the new slapd.conf config file. So now, the only problem remaining when you don't follow the document is that the password won't be correct until next agent run.
So I'm closing that ticket, and I'm marking it a duplicate of #10517 (the cause was the same).
