I'll look at the bug; in the meanwhile, you may want to fix your
configuration by adding
chase-referrals no
overlay chain
chain-uri <the referred URI with no DN>
chain-idassert-bind <info to allow proxyauthz of users>
# ...
See slapo-chain for details. Another option is to use
chase-referrals no
rebind-as-user yes
Thanks Pierangelo
The fact that it worked under debug mode was throwing me off.
Referrals have been fixed and it's working as expected now.
