common LDAP monitor DEBUG behavior

Dear all,

 

 

I need clarification for the common LDAP Monitor provided by Big-F5. The setup is validated and configured well, also works fine, reason to dig into this is to exclude the Big-F5 as possible problem source in a problem where the appliances are in the chain of devices.

 

 

The setup is as follows:

 

Client (EL5/EL6) sssd LDAP -> Load Balancer Big-F5 -> LDAP Server (EL6)

 

the monitor used is configured as follows (I changed the values in here for the post):

 

Parent: LDAP

 

base: dc=example,dc=com

 

filter: (&(objectClass=domain)(dc=example))

 

mandatoryattrs: yes

 

username: cn=monitorUser

 

password: changeme

 

security: ssl

 

 

as mentioned before, the checks work fine and the Appliance acknowledges all Nodes as up and running. if I turn on debugging in the check I can see the content in /var/log/.log like

 

********** Debugging session beginning at: Wed Aug 7 08:00:03 2013

 

 

Arguments 1-2:

 

::ffff:172.27.48.40

 

636

 

 

Environment variables:

 

BASE=dc=example,dc=com

DEBUG=yes

 

FILTER=(&(objectClass=domain)(dc=unix))

 

MANDATORYATTRS=yes

SECURITY=ssl

 

USERNAME=cn=monitorUser

 

--

 

Host URL: ldaps://[::ffff:172.27.48.40]:636

 

Up: 1 entries found.

 

 

which looks fine too, but the checks following this one (was the first entry after enabling debug) don't show the last Line "Up: 1 entries found."

is this a well known and wanted behavior or should it read "Up: 1 entries found" all the time ?

 

thanks for you help ...

 

 

kind regards
