Hi, Using legacy daemon "nslcd" with "aliases: files ldap" switch in nsswitch.conf I can list all aliases from our ldap backend using "getent -s ldap aliases". If I switch to sssd and trying "aliases: files sss" in nsswitch.conf, "getent -s sss aliases" query is empty. also note that in our environment "nslcd.conf" had to be tweaked using these entries for "getent aliases" to work: filter aliases (objectClass=mailRecipient) map aliases rfc822MailMember mail I wonder if sssd support caching aliases database like nslcd does? - If it does, how can I configure sssd to filter and map the aliases queries like nslcd.conf above? - If not will it be supported in the future?
