an ldapsearch shows these lines (note, no quotes around the ldap URL):

olcServerID: 1 ldap://192.168.88.1
olcServerID: 2 ldap://192.168.88.2

i am running fedora 20, and /etc/sysconfig/slapd has the line:

SLAPD_URLS="ldapi:/// ldap://192.168.88.1";

the undocumented nature of this causes a lot of consternation, but
strangely there is no one else offering insight to this.  Thus, we are
left to our wild @$$ guessing.

i believe the quotes in your config are why the string matching is
failing.  try removing the quotes, so that your lines are:

ServerID 1 ldap://ldap1-test.com
ServerID 2 ldap://ldap2-test.com

if that does not work, you will need to iterate through trial and error
until you find a working config.  because i have a dependency on LDAP
for bind/named to work, i use IPs in my configs.  if your DNS is done
elsewhere and you dont have the dependency i have, you should be able to
get things working.
