virtdomains: off
Enable virtual domain support. If enabled, the user’s domain
will be determined by splitting a fully qualified userid at the last
’@’ or ’%’ symbol.
userid refer to "login" user not reverse DNS.
fully qualified userid => johndoe@xxxxxxxxxxx (no dns lookup)
unqualified userid => johndoe (no dns lookup if
sasl_ldap_default_domain* or sasl_ldap_default_realm* and
defaultdomain is set)
* without sasl_ prefix at saslauthd.conf .
With saslauthd.conf:
ldap_default_realm: default.example.org
ldap_filter: (&(objectClass=inetOrgPerson)(mail=%U@%d))
Login with unqualified userid root makes query to
(&(objectClass=inetOrgPerson)(mail=root@xxxxxxxxxxxxxxxxxxx))
With "admins: root" root become global admin.
This example is to salsauthd with LDAP backhend.
