EDIR Gateway Scripts

POWER BROKER RULES:

• transfer_token_file
  • used to transfer gateway related files (needs mods)
  • token files, lock files, etc - between servers

• destroy_token_file
  • used to remove token files from all servers

• pull_token_file
  • used to transfer files between servers (pulls rather than pushes to avoid ssh timeout issues)

Note: All of the Power Broker rules are defined to work with the iplanet owned directory /export/home/iplanet/local/ldap/web/log/. Until such time as the Power Broker rules are modified, all EDIR/AUTHSERV/UPDATE logging needs to share that directory. See log_dir parameter in runtime.cfg file.

Configuration Files

Configuration files are located at: $HOME/EDIR<INST>/config

ldap_admin_actions.cfg

Contains data from which Admin Actions pick list is built. This file can be copied to all servers hosting the same EDIR instance

ldap_left_links.cfg

Contains data used to build links under EDIR banner. This file can be copied to all servers hosting the same EDIR instance.

runtime_common.cfg

subset of runtime configuration elements that are constant between servers hosting gateway - see runtime.cfg; this file can be copied to all servers hosting the same EDIR instance

runtime.cfg

runtime configuration data used by EDIR CGI scripts: this file is server/instance specific; do not copy to other serversv

Parameter Names	Description
all_servers	List of all supported EDIR hosts (sxmpa 2/13/2010 - I cannot find anywhere in the EDIR gateway code where this is read out of runtime.cfg)
authserv_gateway_link	URL to AUTHSERV web gateway
authserv_server_link	URL to server specific AUTHSERV web gateway (Equalizer issue)
debug	0|1: debugging is ON when value is 1

query_servers	List of servers that may respond to query requests (sxmpa 2/13/2010 -This variable should be assigned a single value, which is the host housing the LDAP server queried by this EDIR gateway instance. The EDIR gateway instance is normally co-located with that LDAP server on the same host, but you have the option of choosing an LDAP server on some other host. Assigning this variable a list of hostnames rather than a single hostname appears to work correctly, but examination of the code suggests that behaviour in this case is undefined).
registry_agent	Oracle schema for EDIR registry
registry_db	Oracle instance for EDIR registry
registry_passwd_file	Path reference to registry_agent password file
release	Major release number for EDIR web gateway
slapd_port	Port for iPlanet directory access

update_server	Server(s) that may respond to update requests (local machine issue) (sxmpa 2/13/2010 - the EDIR gateway code reads this variable out of runtime.cfg but does not appear ever to use that value).
version	Gateway instance: TEST PREP or PROD

Note: runtime.cfg files are machine specific. Do not copy between servers.

CGI SCRIPTS: ($HOME/EDIR<INST>/cgi-bin/)

edir_auth CGI script that validates authentication provided by AUTHSERV before putting up the

EDIR "welcome" page.

ldap_admin_assist Generates an HTML form allowing us to assign LDAP entities as SECRETARY to groups

of LDAP records sharing a given department. Utilizes credentials stored in LDAP cookie by ldap_auth. When form is submitted, ldap_admin_assist generates a file of update requests that is passed to ldap_bulk_update. Messages returned by bulk_update become a part of the next display of the HTML form.

ldap_buildings Generates an HTML form used to manage building codes utilized by ldap_loc_update and

stored in uakEmployeeLocator attribute values.

ldap_dept_query (link to ldap_search; name provides context specific behavior)

ldap_dlevelx Generates an HTML form used by individuals with emplAdmin access to add/delete

DLEVELX values to people records.

ldap_filter_help Generates HTML help page (topic: filters)

ldap_history Generates an HTML form used to view EDIR gateway update logs (multiple server issue).

ldap_loc_update Generates an HTML form for maintaining uakEmployeeLocator attribute. Utilizes

credentials stored in LDAP cookie by ldap_auth. Form parses uakEmployeeLocator, breaking it into component parts: MAU, office location, phone and fax. When form is submitted, ldap_loc_update generates a file of update requests that is passed to ldap_bulk_update. Messages returned by bulk_update become a part of the next display of the HTML form.

ldap_log_out Generates log out page that destroys EDIR cookie.

ldap_passwd_help Generates HTML help page (topic: passwords)

ldap_query (link to ldap_search; name provides context specific behavior)

ldap_search Generates an HTML form used to get criteria used to search the directory. Utilizes

credentials stored in LDAP cookie by edir_auth. If no credentials are present, the resulting form contains a subset of the form variables otherwise displayed and queries utilize the gateway interface credentials.

Depending on the name used to call ldap_search (ldap_dept_query and ldap_query are links to ldap_search), the search form is customized to support either "people" or "department" searches.

ldap_sec_update Generates an HTML form used only by account owner to update private question and response.

ldap_seed_department Generates an HTML form allowing creation of "faux" department records ('04' UID extension).

ldap_seed_resource Generates an HTML form allowing creation of ou=resource records.

ldap_seed_routing Generates an HTML form allowing creation of ou=routing records (for @alaska.edu mail routing).

ldap_update Generates an HTML form allowing users to update, add and delete LDAP attribute values for

their own LDAP record and the records of those for which they have update ability. Utilizes the credentials stored in LDAP cookie by ldap_auth. When submitted, ldap_update generates a file of update requests that is passed to ldap_bulk_update. Messages returned by bulk_update become a part of the next display of the HTML form.

ldap_update_help Generates HTML help page (topic: origins of EDIR data, etc.)
