Symptom & Impact

User authenticates but cannot list or write files to the configured Samba share.

Environment & Reproduction

Filesystem permissions, smb.conf ACL rules, or SELinux context mismatch on share path.

Root Cause Analysis

Run: testparm -s, sudo pdbedit -L, and ls -lZ on share directory.

Quick Triage

Ensure smb and nmb services are active and firewalld allows samba service.

Step-by-Step Diagnosis

Capture client/server logs showing denied access reason.

Solution – Primary Fix

Capture corrected SELinux label and SMB configuration.

Solution – Alternative Approaches

Set proper ownership/ACLs on share path and confirm unix permissions.

Verification & Acceptance Criteria

Apply SELinux context: sudo semanage fcontext -a -t samba_share_t ‘/srv/samba(/.*)?’ && sudo restorecon -Rv /srv/samba.

Rollback Plan

Restart services: sudo systemctl restart smb nmb.

Prevention & Hardening

Test read/write using smbclient and from a Windows/Linux SMB client.

Related Errors & Cross-Refs

Version-control smb.conf and enforce SELinux context policies with automation.
