+ LDAP Lookup of Connection Parameters
+
+
+ LDAP connection parameter lookup
+
+
+
+ If libpq has been compiled with LDAP support (option
+ for configure)
+ it is possible to retrieve connection options like host
+ or dbname via LDAP from a central server.
+ The advantage is that if the connection parameters for a database change,
+ the connection information doesn't have to be updated on all client machines.
+
+
+
+ LDAP connection parameter lookup uses the connection service file
+ pg_service.conf (see ).
+ A line in a pg_service.conf stanza that starts with
+ ldap:// will be recognized as an LDAP URL and an LDAP
+ query will be performed. The result must be a list of keyword =
+ value pairs which will be used to set connection options.
+ The URL must conform to RFC 1959 and be of the form
+
+ ldap://[hostname[:port]]/search_base?attribute?search_scope?filter
+
+ where hostname
+ defaults to localhost and
+ port defaults to 389.
+
+
+
+ Processing of pg_service.conf is terminated after
+ a successful LDAP lookup, but is continued if the LDAP server cannot be
+ contacted. This is to provide a fallback with
+ further LDAP URL lines that point to different LDAP
+ servers, classical keyword = value pairs, or
+ default connection options.
+ If you would rather get an error message in this case, add a
+ syntactically incorrect line after the LDAP URL.
+
+
+
+ A sample LDAP entry that has been created with the LDIF file
+
+ version:1
+ dn:cn=mydatabase,dc=mycompany,dc=com
+ changetype:add
+ objectclass:top
+ objectclass:groupOfUniqueNames
+ cn:mydatabase
+ uniqueMember:host=dbserver.mycompany.com
+ uniqueMember:port=5439
+ uniqueMember:dbname=mydb
+ uniqueMember:user=mydb_user
+ uniqueMember:sslmode=require
+
+ might be queried with the following LDAP URL:
+
+ ldap://ldap.mycompany.com/dc=mycompany,dc=com?uniqueMember?one?(cn=mydatabase)
