H1: Upgrading from 2.5.x
The following sections attempt to document the steps you will need to take
in order to upgrade from the latest 2.5.x OpenLDAP version.
The normal upgrade procedure, as discussed in the {{SECT:Maintenance}}
section, should of course still be followed prior to doing any of this.
H2: ppolicy overlay
The pwdCheckModule option has been moved to the overlay configuration.
Existing settings in password policy entries will be ignored. It will be
necessary to use pwdUseCheckModule instead and add this configuration
directive to the overlay when upgrading if it is currently in use.
H2: lloadd backends
Backends for lloadd are now grouped in tiers specifying the balancing
strategy. OpenLDAP 2.5 configurations must be updated to account for this
change.
H2: monitor backend
In 2.5 and prior, the managedInfo attribute in the cn=Log entry could be
used to change the loglevel of the slapd process. In 2.6, monitorLogLevel
can be used to change the slapd log level and monitorDebugLevel can be used
to change the slapd debug level.
H2: contrib modules
If still using the lastbind overlay with olcLastBindPrecision (when
olcLastBindForwardUpdates is needed), you will need to configure
precision on its backend entry instead and the overlay will honour it.
The old attribute is no longer accepted or supported.
