SAS® Integration Technologies: Administrator's Guide (LDAP Version)

Using a Configuration File to Define the Metadata (IOM
Bridge)
For LDAP, if you do not use a metadata server as the metadata repository, you can create a flat configuration file that
contains the object definitions for an IOM Bridge server configuration. The configuration file must then be installed
on the server and on each client machine.
Note: If your configuration requires more than one or two servers, or if multiple clients will be using the servers, we
strongly recommend the use of LDAP as a central metadata repository. The use of LDAP also gives you the ability to
use access control lists to control access to the servers in your enterprise.
To define an IOM Bridge server configuration using a configuration file:
1.
Use a text editor to code the configuration file. At a minimum, the file must define a server object and a
spawner object. You can also define one more SAS login objects, and/or logical name objects. To create the
file:
♦ Refer to the attribute descriptions for each object type:
◊ Attributes for sasLogin
◊ Attributes for sasLogicalNameInfo
◊ Attributes for sasServer
◊ Attributes for sasSpawner
♦ Refer to the following examples:
◊ Example Minimal Configuration
◊ Example Server and Spawner
◊ Example Using Logical Names
◊ Example UUID Generator
♦
Use the LDAP Data Interchange Format (LDIF), format, which has the following syntax rules:
◊ Start each entry in column one.
◊ To indicate a comment line, place '#' in column one.
◊ Use the following general format for each entry: "attribute: value".
◊ If an entry spans multiple lines, insert a blank in the first column of each continuation line.
The blank in column one is a continuation character and is consumed by the LDIF file parser.
Therefore, it should not be considered part of the entry.
◊ A blank line must precede a distinguished name (exclude comment lines and the first
distinguished name in the file). In LDIF, the DN is required to identify the beginning of the
next object class definition. The spawner's LDIF parser relies on this requirement in order to
separate object class definitions. The DN name can be any value.
◊ Two consecutive blank lines indicate the end of the configuration file definitions.
2. Save the file with a name of your choice (for example, objspawn.cfg).
3. Install the file on the server machine and on each client machine.
You can now start the spawner. For instructions, refer to Starting the Spawner.
