Documentation makes reference to `tls_ciphersuite=` option for
olcSyncrepl/syncrepl settings however I got an error when trying to use it.

On a hunch, I tried using `tls_cipher_suite=` instead matching the style of the
equivalent ldap.conf setting and this worked.

Confirmed what the code was doing here:

http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=blob;f=servers/slapd/config.c#l1428

slapd-config(5), slapd.conf(5) are affected as well as the admin guide,
potentially slapd-meta(5) and slapd-ldap(5) too if those backends reuse the same
config code.
