nss.alias.source

This configuration parameter specifies the source to look up aliases, and you specify one of the following values:

  • nismaps (default)
  • mail
  • proxyaddresses

To look up the alias from an Active Directory user object, use the mail or proxyAddresses value. Because proxyaddresses is a custom attribute, you need to also include it in the adclient.custom.attributes.user parameter or else the alias source reverts to nismaps.

Using the mail or proxyAddresses values don't work with users in a one-way trusted forest.
