NAME
slapo-auditlog - Audit Logging overlay to slapd
SYNOPSIS
/etc/ldap/slapd.conf
/etc/ldap/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 informa-
tion 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 re-
questor'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 in-
dicates an internal slapd operation.
