Usage: ./check_ldap.pl -H -l login -x passwd -p -s -t -V -h, --help print this help message -H, --hostname=HOST name or IP address of host to check -l, --login=LOGIN Login for ldap authentication (if not specified ./check_ldap.pl uses anonymous) -x, --passwd=PASSWD Password for ldap authentication -p, --port=PORT LDAP port (Default 389) -s, --ssl LDAPS (Default false, if true, default port is 636 ) -t, --timeout=INTEGER timeout in seconds (Default: 15) -V, --version prints version number Note : The script will return
OK if we are able to connect and bind to the LDAP server, WARNING if we are able to connect but not bind to the LDAP server CRITICAL if we aren't able to connect to the LDAP server
In case the script just fails with CRITICAL and no error msg, it is because $ldap has not be created due to SSL cipher negociation problem. Patch below fixes the issue: --- check_ldap.pl.orig 2024-11-01 09:43:44.616030489 +0100 +++ check_ldap.pl 2024-11-01 09:43:51.356022937 +0100 @@ -113,9 +113,9 @@ } } else { if (defined($o_port)) { - $ldap = Net::LDAPS->new( $o_host, port => $o_port, version => 3, timeout => $o_timeout ); + $ldap = Net::LDAPS->new( $o_host, port => $o_port, version => 3, timeout => $o_timeout, sslversion => 'tlsv1_2' ); } else { - $ldap = Net::LDAPS->new( $o_host, port => $o_ldaps_port, version => 3, timeout => $o_timeout ); + $ldap = Net::LDAPS->new( $o_host, port => $o_ldaps_port, version => 3, timeout => $o_timeout, sslversion => 'tlsv1_2' ); } }
Thanks, no prolems here. My Debian needed a `sudo apt-get install libnet-ldap-perl`.
