logfile

OpenLDAP logs via syslogd (using LOCAL4) in all cases (see loglevel for configuration information on streaming syslogd LDAP messages to a separate file). In addition the logfile directive may be used to create a separate file containing just LDAP log information. Even when this directive is used OpenLDAP will also log the same information via syslogd. Example:

logfile /path/to/ldap/log/file

# file must exist prior to starting OpenLDAP
touch /path/to/ldap/log/file
chown ldap:ldap /path/to/ldap/log/file

Up Arrow

loglevel

OpenLDAP logs via syslogd LOCAL4. To stream the LDAP log to a separate file from syslog add a line like this to syslog.conf (normally /etc/syslog.conf):

# add to syslog.conf
local4.* /var/log/ldap.log

# create an empty log file
touch /var/log/ldap.log

# restart syslogd
killall -HUP syslogd
OR
/etc/rc.d/syslogd restart

The above command will log all levels of local4 (OpenLDAP) output to /var/log/ldap.log. Alternatively the logfile directive may be used.

The OpenLDAP logging level is set using the following directive:

loglevel number | hex-value | log-name

The possible values for number, hex-value and log-name are:

number hex-value log-name Logging description
-1 0xFFFF
enable all logging
0 0x0000 - logging inhibited - no logging occurs including critical errors. Not recommended.
1 0x1 acl trace function calls
2 0x2 packets debug packet handling
4 0x4 args heavy trace debugging
8 0x8 conns connection management
16 0x10 BER print out packets sent and received
32 0x20 filter search filter processing
64 0x40 config configuration file processing
128 0x80 ACL access control list processing
256 0x100 stats stats log connections/operations/results
512 0x200 stats2 stats log entries sent
1024 0x400 shell print communication with shell backends
2048 0x800 parse print entry parsing debugging
4096 0x1000 cache caching (unused)g
8192 0x2000 index indexing (unused)
16384 0x4000 sync print syncrepl (replica) logging
32768 0x8000 none A misnomer - it will log message that are not categorized including curial messages

The loglevel directive takes a single value or a space separated list of values, each value may be any combination of number, hex-value or log-name from the table above. The results are OR'd together. It is also possible to set multiple entries in either the number or hex-value as shown in the following examples:

loglevel 255
# sets 1, 2, 4, 8, 16, 32, 64 and 128
# adds all the numbers

loglevel 2176
# 2048 + 128
loglevel 296
# 256 + 32 + 8

# using single hex-value (128)
loglevel 0x80

# multiple hex-values (1 + 128)
loglevel 0x81
# same result as
loglevel 0x1 0x80

# using log-name (single value)
loglevel acl

# multiple log-name values
loglevel acl sync

# combined
loglevel 1 0x40 conns

If no loglevel directive is defined the log defaults to 256 (stats only).

Note: With the -1 setting slapd logs ferocious amounts of data. Reduce this value as quickly as possible to only those items you are interested in or buy new discs - lots of new discs.
