kevinveenbirkenbachandClaude Opus 5.5 c925150848 fix(web-app-openbao): ship the LDAP auth method as an external plugin
OpenBao 2.7 removed the builtin LDAP auth engine from the server binary
(openbao/openbao GH-3882). `bao auth enable ldap` answered
"plugin not found in the catalog: ldap" and the deploy stopped there.

The role now builds its own image. A multi-stage Dockerfile copies the
openbao-plugin-auth-ldap binary out of the image declared as the
`auth-ldap` service entry into /opt/openbao/plugins. A second server
config file, plugins.hcl, names that directory and registers the plugin
declaratively. It sets plugin_auto_register = true explicitly: the image
starts the server with a config directory, and on that path 2.7.1 does
not apply the documented default, so without the line the catalog stays
empty. The Dockerfile sets the file mode in a helper stage instead of
COPY --chmod, which only BuildKit accepts.

The mount is enabled with -plugin-version=latest, so it follows whichever
plugin version the image ships. A mount created by the former builtin
engine is tuned and reloaded onto the plugin, which needs `update` on
sys/plugins/reload/backend in the ansible-admin policy.

The LDAP tasks move into tasks/addons/auth-ldap.yml and the plugin is
declared under meta/addons as a required addon bridged to `ldap`. Its
Playwright spec logs in through the mount and asserts that sys/auth
reports an external running plugin version.
