TLS failing?

I'm setting up new LDAP servers with replication, and I configured TLS, but I see this in my log:

May 11 14:29:07 nyprldap1 slapd[8867]: conn=2572 op=1 BIND dn="cn=manager,dc=about,dc=com" method=128 May 11 14:29:07 nyprldap1 slapd[8867]: conn=2572 op=1 BIND dn="cn=manager,dc=about,dc=com" mech=SIMPLE ssf=0

Does this mean that TLS is failing and it is falling back to ssf=0? I think my master is configured to not allow unencrypted connections:

disallow bind_anon require bind security simple_bind=128
