The query is speci- fied by the target-specific variable `filter' and, optionally, by the tar- get-specific variable `base'. The attributes queried can be specified in the comma-separated list `attrs'. The TCP port of the LDAP server and the LDAP version to be used can be specified by the variables `port' and `version'. The probe can issue the starttls command to convert the connection into en- crypted mode, if so instructed by the `start_tls' variable. This requires the 'IO::Socket::SSL' perl module to be installed. The probe can also optionally do an authenticated LDAP bind, if the `binddn' variable is present. The password to be used can be specified by the target-specific variable `password' or in an external file. The loca- tion of this file is given in the probe-specific variable `passwordfile'. See Smokeping::probes::passwordchecker(3pm) for the format of this file (summary: colon-separated triplets of the form `<host>:<bind-dn>:<pass- word>') The probe tries to be nice to the server and does not send authentication requests more frequently than once every X seconds, where X is the value of the target-specific "min_interval" variable (1 by default). VARIABLES Supported probe-specific variables: forks Run this many concurrent processes at maximum Example value: 5 Default value: 5 offset If you run many probes concurrently you may want to prevent them from hitting your network all at the same time. Using the probe-specific offset parameter you can change the point in time when each probe will be run. Offset is specified in % of total interval, or alternatively as 'random', and the offset from the 'General' section is used if nothing is specified here. Note that this does NOT influence the rrds itself, it is just a matter of when data acquisition is initiated. (This vari- able is only applicable if the variable 'concurrentprobes' is set in the 'General' section.) Example value: 50% passwordfile Location of the file containing usernames and passwords. Example value: /some/place/secret stepDuration of the base interval that this probe should use, if different from the one specified in the 'Database' section. Note that the step in the RRD files is fixed when they are originally generated, and if you change the step parameter afterwards, you'll have to delete the old RRD files or somehow convert them. (This variable is only applicable if the variable 'concurrentprobes' is set in the 'General' section.) Example value: 300 Supported target-specific variables: /^influx_.+/ This is a tag that will be sent to influxdb and has no impact on the probe measurement. The tag name will be sent without the "influx_" pre- fix, which will be replaced with "tag_" instead. Tags can be used for filtering. Example value: influx_location = In the basement attrs The attributes queried. Example value: uid,someotherattr baseThe base to be used in the LDAP query Example value: dc=foo,dc=bar binddn If present, authenticate the LDAP bind with this DN. Example value: uid=testuser,dc=foo,dc=bar filter The actual search to be made Example value: uid=testuser This setting is mandatory. mininterval The minimum interval between each query sent, in (possibly fractional) second s. Default value: 1 password The password to be used, if not present in <passwordfile>. Example value: mypass pings How many pings should be sent to each target, if different from the global value specified in the Database section. Note that the number of pings in the RRD files is fixed when they are originally generated, and if you change this parameter afterwards, you'll have to delete the old RRD files or somehow convert them. Example value: 5 portTCP port of the LDAP server Example value: 389 scheme LDAP scheme to use: ldap, ldaps or ldapi Example value: ldap Default value: ldap scope The scope of the query. Can be either 'base', 'one' or 'sub'. See the Net::LDAP documentation for details. Example value: one Default value: sub start_tls If true, encrypt the connection with the starttls command. Disabled by default. Example value: 1 timeout LDAP query timeout in seconds. Example value: 10 Default value: 5 verify The TLS verification level. Can be either 'none', 'optional', 're- quire'. See the Net::LDAPS documentation for details. Example value: optional Default value: require version The LDAP version to be used. Example value: 3 AUTHORS Niko Tyni <ntyni@iki.fi> BUGS There should be a way of specifying TLS options, such as the certificates involved etc. The probe has an ugly way of working around the fact that the IO::Socket::SSL class complains if start_tls() is done more than once in the same program. But It Works For Me (tm). 2.9.0 2026-08-04 Smokeping_probes_LDAP(3)
