LDAP Server Connections Closing Immediately

[Jonathan Gryak]

Hi Alan,
Sorry for not elaborating. I was primarily concerned with the debug
message: rlm_ldap (ldap): 0 of 0 connections in use.  You  may need to
increase "spare"

I suppose that I would expect the slot count in the pool to decrease or
increase with each connection used, as when the server initially starts up
the number of available slots decreases from 32 to 28.

Regarding the "re-use LDAP connections", I thought the lifetime=0 setting
would mean that an existing slot would used, and that slot would be
indicated in the debug output for each LDAP connection. I though perhaps
that the "1 of 32 pending slots used" message indicated that a new thread
was being created each time, rather than reusing one from the pool.
