| 3 | +Tests for auth manager PKI access to postgres. |
| 4 | +
|
| 5 | +This is an integration test for QGIS Desktop Auth Manager postgres provider that |
| 6 | +checks if QGIS can use a stored auth manager auth configuration to access |
| 7 | +a PKI protected postgres. |
| 8 | +
|
| 9 | +Configuration form the environment: |
| 10 | +
|
| 11 | + * QGIS_POSTGRES_SERVER_PORT (default: 55432) |
| 12 | + * QGIS_POSTGRES_EXECUTABLE_PATH (default: /usr/lib/postgresql/9.3/bin) |
| 13 | +
|
