Authenticate to LDAP using creds are configured - #327
Conversation
In case where connection to ldap is guarded behind basic auth, unstructured controller should be able to honor that and check for user details from ldap server. Signed-off-by: vinamra28 <vinjain@redhat.com>

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The PR adds LDAP credential support, but it can silently use anonymous access with incomplete credentials, expose credentials over unencrypted LDAP, hang during authentication, and mark oversized files as processed when they were not stored. These security, availability, and correctness risks should be fixed before merge. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Reject partial LDAP credentials instead of selecting anonymous bind.
When either LdapUserName or LdapPassword is empty, the client performs UnauthenticatedBind(""). This can silently ignore a configured username when LDAP_PASSWORD is missing. Reject partial credentials during initialization and reconnection. Allow anonymous binding only when both values are empty.

Require encrypted LDAP for credentialed binds.
With ldap://, Bind sends credentials in an LDAP simple bind over TCP. When credentials are configured, reject ldap:// or call certificate-validated StartTLS before both Bind calls. Update the sample and API documentation to use ldaps://.

github.com/go-ldap/ldap/v3 v3.4.13 Conn SetTimeout Bind implementation
💡 Result:
In the go-ldap/ldap/v3 library (specifically version 3.4.13), the SetTimeout method and the Bind method are separate components of the Conn struct, and they interact in the context of request lifecycle management [1][2][3]. SetTimeout implementation: The SetTimeout method configures a duration used for individual LDAP request timeouts, not for the underlying TCP connection timeout [4][3]. When a timeout is set (greater than zero), the library initiates a background goroutine for each request sent via the connection [3]. This goroutine sleeps for the specified duration and, if the request has not yet completed, sends a MessageTimeout packet to the connection's processing loop [3]. This causes the library to stop waiting for the server's response, close the associated response channel, and return an error (typically "ldap: connection timed out") to the caller [3]. Bind implementation: The Bind method performs a simple bind operation using the provided username and password [1]. Internally, it creates a SimpleBindRequest and calls the SimpleBind method [1]. Because SimpleBind uses the internal message sending mechanism (typically sendMessage), it is subject to the request timeout configured by SetTimeout [3]. If the Bind request takes longer than the duration specified in SetTimeout, the background timer will trigger, and the Bind call will return an error [4][3]. Important Clarifications: 1. Terminology: Users often confuse SetTimeout with connection-level timeouts [4]. As noted in library discussions, SetTimeout specifically controls the timeout for an individual LDAP operation [4]. To control the initial TCP connection timeout, users should use a custom dialer (e.g., net.Dialer) passed via DialWithDialer when establishing the connection [4]. 2. Versioning: The implementation of these mechanics remains consistent across the v3.x releases, including v3.4.13 [5][2][3]. 3. Best Practice: Because SetTimeout is a global setting on the Conn object, it applies to all subsequent operations performed on that connection until changed [3]. If you need different timeouts for different operations, consider that SetTimeout is not thread-safe for concurrent adjustments and is intended to be a persistent configuration for the connection's operations [3].

Set an LDAP operation timeout for every bind path.
The 5-second net.Dialer timeout does not limit LDAP responses. A bind can block when the server accepts TCP but does not respond. Set an operation timeout on both the initial and replacement connections before binding.

Do not record skipped oversized files as successfully processed.
storeFile returns (false, nil) when the downloaded content exceeds maxFileSize. It then returns before storing content or permissions. This code appends the file whenever err == nil, so storedFiles can contain a file that was not processed. Make storeFile return a separate processed/skipped status, and append only when processing completed. Preserve appending deduplicated files.
