   message: <<EOM
 Configure your sshd_config(5) with the following to use opkssh for authorization:
 
   AuthorizedKeysCommand %%PREFIX%%/bin/opkssh verify %u %k %t
   AuthorizedKeysCommandUser %%USER%%
 
 opkssh uses the '%%PREFIX%%/etc/opk' directory, where providers and identities are stored.
 Neither the directory nor the files are created automatically, so you must create them
 yourself. After creating the 'auth_id' and 'providers' files, they must have the
 following permissions:
 
   chown root:%%GROUP%% %%PREFIX%%/etc/opk/auth_id
   chmod 640 %%PREFIX%%/etc/opk/auth_id
   chown root:%%GROUP%% %%PREFIX%%/etc/opk/providers
   chmod 640 %%PREFIX%%/etc/opk/providers
+
+Users attempting to use opkssh from jails, please add "allow.mlock" or it will not run.
 EOM
