SLAPO-AUDITLOG(5)

NAME
slapo-auditlog - Audit Logging overlay to slapd

SYNOPSIS
/usr/pkg/share/examples/openldap/slapd.conf

/usr/pkg/share/examples/openldap/slapd.d

DESCRIPTION
The Audit Logging overlay can be used to record all changes on a given backend database to a specified log file. Changes are logged as standard LDIF, with an additional comment header providing six fields of information about the change. A second comment header is added at the end of the operation to note the termination of the change.

For Add and Modify operations the identity comes from the modifiersName associated with the operation. This is usually the same as the requestor's identity, but may be set by other overlays to reflect other values.

CONFIGURATION
This slapd.conf option applies to the Audit Logging overlay. It should appear after the overlay directive.

auditlog <filename>
    Specify the fully qualified path for the log file.

olcAuditlogFile <filename>
    For use with cn=config

COMMENT FIELD INFORMATION
The first field is the operation type.
The second field is the timestamp of the operation in seconds since epoch.
The third field is the suffix of the database.
The fourth field is the recorded modifiersName.
The fifth field is the originating IP address and port.
The sixth field is the connection number. A connection number of -1 indicates an internal slapd operation.

EXAMPLE
The following LDIF could be used to add this overlay to cn=config (adjust to suit)

    dn: olcOverlay=auditlog,olcDatabase={1}mdb,cn=config
    changetype: add
