There's a mismatch between the documentation for the sssvlv-maxpercon option and the actual configuration option name.
The man page documentation for slapo-sssvlv states that the maximum number of concurrent paged search requests per connection option is 'sssvlv-maxperconn'. For an LDAP-based configuration the option is 'olcSssVlvMaxPerConn' but for a slapd.conf based configuration the option is 'sssvlv-maxpercon' (note only one 'n', not two).
