B.2 Core Script Process
When Point of Service terminals are being set up in a branch or subsidiary, the
posleases2ldap.pl script must be started as a daemon on the Branch Server for
the relevant branch. All other scripts are controlled by this script.
The interplay of scripts on the Branch Server occurs as follows:
1 posleases2ldap.pl is started directly on the Branch Server. If the
2 posleases2ldap.pl is running as a daemon process and monitors the /var/

entered in the directory, it generates new entries for the scWorkstation object
class under the relevant scLocation object. The first items filled out are the
required attributes macAddress, ipHostNumber, and the cn for the entry.
The terminal's IP address and name are automatically generated, and the MAC
address is taken from the leases file. These entries are like an outline.
the pattern hwtype.MAC that are being uploaded by Point of Service terminals
registered from the DiskNetboot system. The Point of Service hardware type is
specified in these files. For more information, see Section 7.8, "Booting the Point
of Service Terminal" (page 102). If any files of this type are found, the following
process runs:
4a Using the MAC address, the relevant scWorkstation entry is looked up
in the LDAP directory. With the content of the hwtype.MAC file, the cor-
responding scRefPc (the reference hardware type in the global container)
is searched. In the scRefPc object (named after the hardware type), the
image type for this hardware type is specified as a reference to a
scPosImage object in the attribute scPosImageDn, which points to the
reference image in the global container. The information about the reference
hardware and image are then added to the scWorkstation object as dis-
