| ## Defining Attribute Trigger Servers Some attribute types require the support of an outside server either to verify input attribute values or to supply output attribute values when those values are stored in an external database. Such a server could, for example, connect a legacy registry system to the DCE registry. The attribute trigger facility provides for automatic calls to outside DCE servers, known as attribute triggers. Trigger servers are invoked automatically when an attribute associated with a trigger server is queried or updated. Note that access to information maintained by a trigger server is controlled entirely by that server. Note: Update trigger servers are not supported in this release. To associate an attribute type with a trigger server, use the -trigtype and -trigbind dcecp xattrschema options. More: The -trigtype Option The -trigbind Option ###
