Hosteddomains Option
From MsgServerDocWiki
Whether the MMP should use Hosted Domains.
If you are using the Sun Messaging Server directory schema (Sun LDAP Schema, v1 or Sun LDAP Schema, v2), this should be set to the default.
If set to 0, then the MMP assumes the server supports only one domain and LdapUrl points to a directory subtree containing all users supported by the server, each user with a unique UID. Setting HostedDomains to "0" is not recommended as even a small company is likely to eventually go through a name change or acquisition where support for multiple domains would be helpful.
When set to 1, the MMP honors the following additional options from the MTA's option.dat configuration file:
ldap_schemalevel ldap_domain_filter_schema1 ldap_domain_filter_schema2 ldap_attr_domain1_schema2 ldap_attr_domain2_schema2 ldap_global_config_templates ldap_attr_domain_search_filter ldap_domain_attr_basedn ldap_domain_attr_canonical ldap_domain_attr_alias
These settings may be used to enable Sun LDAP Schema, v2 with the MMP.
The default value is: 1
