# postgres\_ident\_conf
Use the `postgres_ident_conf` InSpec audit resource to test the client authentication data defined in the pg_hba.conf file.
## Availability
### Installation
This resource is distributed along with InSpec itself. You can use it automatically.
### Version
This resource first became available in v1.31.0 of InSpec.
## Syntax
An `postgres_ident_conf` InSpec audit resource block declares client authentication data that should be tested:
describe postgres_ident_conf.where { pg_username == 'filter_value' } do
its('attribute') { should eq ['value'] }
end
where
* `'attribute'` is a attribute in the pg ident configuration file
* `'filter_value'` is the value that is to be filtered for
* `'value'` is the value that is to be matched expected
## Properties
'conf_file', 'map_name', 'params', 'pg_username', 'system_username'
## Property Examples
### map_name([String])
`address` returns a an array of strings that matches the where condition of the filter table
describe pg_hba_conf.where { pg_username == 'name' } do
its('map_name') { should eq ['value'] }
end
### pg_username([String])
`pg_username` returns a an array of strings that matches the where condition of the filter table
describe pg_hba_conf.where { pg_username == 'name' } do
its('pg_username') { should eq ['value'] }
end
### system_username([String])

describe postgres_ident_conf.where { pg_username == 'name' } do
its('system_username') { should eq ['value'] }
its('map_name') { should eq ['value'] }
