SLAPO-LASTBIND(5) File Formats Manual SLAPO-LASTBIND(5) NAME slapo-lastbind - lastbind overlay to slapd SYNOPSIS ETCDIR/slapd.conf DESCRIPTION The lastbind overlay to slapd(8) allows recording the timestamp of the last successful bind to entries in the directory, in the authTimestamp attribute. The overlay can be configured to update this timestamp only if it is older than a given value, thus avoiding large numbers of write operations penalizing performance. One sample use for this overlay would be to detect unused accounts. Now that OpenLDAP has native support for most of this functionality, storing the value in pwdLastSuccess to better interact with the Behera Password Policy draft 10. Unless you require lastbind_forward_updates, you should consider using that instead. CONFIGURATION The config directives that are specific to the lastbind overlay must be prefixed by lastbind-, to avoid potential conflicts with directives specific to the underlying database or to other stacked overlays. overlay lastbind This directive adds the lastbind overlay to the current data- base, see slapd.conf(5) for details. This slapd.conf configuration option is defined for the lastbind over- lay. It must appear after the overlay directive: lastbind-precision <seconds> The value <seconds> is the number of seconds after which to up- date the authTimestamp attribute in an entry. If the existing value of authTimestamp is less than <seconds> old, it will not be changed. If this configuration option is omitted, the auth- Timestamp attribute is updated on each successful bind opera- tion. lastbind_forward_updates Specify that updates of the authTimestamp attribute on a con- sumer should be forwarded to a provider instead of being written directly into the consumer's local database. This setting is only useful on a replication consumer, and also requires the up- dateref setting and chain overlay to be appropriately config- ured. EXAMPLE This example configures the lastbind overlay to store authTimestamp in all entries in a database, with a 1 week precision. Add the following to slapd.conf(5): database <database> # ... overlay lastbind lastbind-precision 604800 slapd must also load lastbind.la, if compiled as a run-time module; FILES ETCDIR/slapd.conf default slapd configuration file SEE ALSO slapd.conf(5), slapd(8). IETF LDAP password policy proposal by P. Behera, L. Poitou and J. Sermersheim: documented in IETF document "draft-behera-ldap-password- policy-10.txt". The slapo-lastbind(5) overlay supports dynamic configuration via back- config. ACKNOWLEDGEMENTS This module was written in 2009 by Jonathan Clarke. It is loosely de- rived from the password policy overlay. OpenLDAP LDVERSION RELEASEDATE SLAPO-LASTBIND(5)
