## LDAP Limit Quota Tables

LDAP-based quota tables (source-type of "ldap") can only be used for limit tables, not for tally tables. The frequent updates needed for maintaining tally tables mean that LDAP is not well-suited to handle tally table storage.

The `mod_quotatab_ldap` module supports the "ldap" string for the source-type parameter of the `QuotaLimitTable` configuration directive.

To enable LDAP-provisioned limit tables, you need to configure `mod_ldap` to lookup the proper attribute using the `LDAPDoQuotaLookups` configuration directive.

The LDAP attribute to be looked up (named `ftpQuota` by default) should contain a comma-separated list of values, in the following order:

      per_session,limit_type,bytes_in_avail,bytes_out_avail,bytes_xfer_avail,
        files_in_avail,files_out_avail,files_xfer_avail

For example:

      "false,hard,100,100,100,100,100,100"

An example `proftpd.conf` configuration might look like:

      <IfModule mod_quotatab.c>
        <IfModule mod_quotatab_ldap.c>
          # Enable LDAP quota lookups
          LDAPDoQuotaLookups on

          # Use an LDAP-based limit table.  Note that there is no additional
          # information supplied after the source-type: this is intentional.
          # mod_ldap handles the rest.
          QuotaLimitTable ldap:
        </IfModule>

        # Use a file-based tally table
        QuotaTallyTable file:/usr/local/proftpd/ftpquota.tallytab
      </IfModule>
