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
       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
              objectClass: olcOverlayConfig
              objectClass: olcAuditLogConfig
              olcOverlay: auditlog
              olcAuditlogFile: /tmp/auditlog.ldif
