- From last night's logs, it sure looks like it's just not even
talking to the ldap server before the failure, other than to do
its initial auth.

On a normal interval, I see the following ldap activity:

1. no-op bind/unbind as grouper user (presumably to check auth)
2. bind; search for (&(cn=GrouperSystem)) [no results]; unbind
3. bind; search for
(&(uid=GrouperSystem)(objectClass=riceEduPerson)) [no results];
4. bind;
search for
[no results];
search for (objectClass=groupOfUniqueNames) [28242 results];
search for (objectClass=organizationalUnit) [9541 results];

On a failed run, I see only the first three binds. Not even an
attempt to bind and search the provisioning base for the
existing data.

I don't know if that's at all helpful. I'll see if I can get
anything from the postgresql logs.
