Bug Fixes – April 18, 2026

Summary

✅ All reported bugs fixed and verified

---

Bug #1: Recent Logins Missing Usernames

Reported: "Recent Logins hat keine user name drin!"

Root Cause:

• Frontend was looking for login.user field
• Backend API returns login.username field (different name)

Fix Applied:

• Updated frontend/app/identities/page.tsx line 559
• Changed to: (login as any).username || (login as any).user
• Added fallback for compatibility

Verification:

Backend Response: {"username":"administrator","login_str":"Wed Apr 15 22:45 2026"}
Frontend Now Shows: → administrator (Wed Apr 15 22:45 2026)
Status: ✅ FIXED

Bug #2: File Properties Owner – No Name Autocomplete

Reported: "File Properties Owner macht keine vervollständigung der namen"

Root Cause:

• Owner input field was plain <input type="text">
• No autocomplete or data suggestions
• Users had to type UID numbers or guess names

Fix Applied:

1. Added state variables to track available users/groups:

   const [usernames, setUsernames] = useState<string[]>([])
   const [groupnames, setGroupnames] = useState<string[]>([])
   

2. Added loadUsersAndGroups() function to fetch from API:

   • Calls /api/identities/users on component mount
   • Calls /api/identities/groups on component mount
   • Extracts username and groupname arrays

3. Updated Owner input field:

   <input list="owners-list" ... />
   <datalist id="owners-list">
     {usernames.map(name => <option key={name} value={name} />)}
   </datalist>
   

4. Added same for Group field

Verification:

Available Users: root, administrator, testuser, wsdd2, nobody
Available Groups: root, sudo, administrator, tape, ...
Owner Dropdown: ✅ NOW shows autocomplete
Group Dropdown: ✅ NOW shows autocomplete
Status: ✅ FIXED

Bug #3: File Properties Group – Same Autocomplete Issue

Reported: Same as #2, applies to both Owner and Group

Status: ✅ FIXED (both handled in same code change)
