[Pkg-openldap-devel] Bug#812515: slapd: upgrading slapd with several databases

[Samuel Thibault]

Package: slapd
Version: 2.4.31-2+deb7u1
Severity: serious
Justification: database upgrade failed

Hello,

I at last upgraded our old ldap server to wheezy (yes, that's already
old, but the kind of upgrade issues we are having as described here
doesn't motivate to do it), and it went wrong:

  Backing up /etc/ldap/slapd.d in /var/backups/slapd-2.4.23-7.3+deb6u2... done.
  Moving old database directories to /var/backups:
  Loading from /var/backups/slapd-2.4.23-7.3+deb6u2: 
  - directory dc=aquilenet,dc=fr... failed.

Loading the database from the LDIF dump failed with the following
error while running slapadd:
    56a4e83c olcDbDirectory: value #0: invalid path: No such file or directory
    56a4e83c config error processing olcDatabase={2}hdb,cn=config: olcDbDirectory: value #0: invalid path: No such file or directory
    slapadd: bad configuration directory!

What is notable with our ldap database is that it has one domain
(dc=aquilenet,dc=fr, in {1}hdb) in /var/lib/ldap:

olcDbDirectory: /var/lib/ldap

, and another domain (dc=girondix,dc=net, in {2}hdb) in
/var/lib/ldap/NET:

olcDbDirectory: /var/lib/ldap/NET

Since the upgrade scripts move the content of /var/lib/ldap out, loading
the second database fails since /var/lib/ldap/NET doesn't exist.

The crude way we have fixed it is to add, in load_databases, just after
checking that $dbdir is empty, an mkdir /var/lib/ldap/NET, so that the
load succeeds, I then get:

  BBacking up /etc/ldap/slapd.d in /var/backups/slapd-2.4.23-7.3+deb6u2... done.
  Moving old database directories to /var/backups:
  Loading from /var/backups/slapd-2.4.23-7.3+deb6u2: 
target is /var/lib/ldap
  - directory dc=aquilenet,dc=fr... done.
  - chowning database directory (openldap:openldap)... done
target is /var/lib/ldap/NET
  - directory dc=girondix,dc=net... done.
  - chowning database directory (openldap:openldap)... done

I guess a proper way to do it would be to just create all olcDbDirectory
directories recorded in the database configuration.
