Based on your persistent issues, let's implement a thorough solution to regain full admin access:

Step 1: Verify Complete Group Assignments

Run this SQL to ensure all admin privileges:

sql

-- For existing admin user
UPDATE res_users SET 
    password = 'pbkdf2_sha512$600000$ExampleSalt$ExampleHash',
    active = true,
    share = false
WHERE login = 'admin';

-- Add to ALL security groups (critical for full access)
INSERT INTO res_groups_users_rel (gid, uid)
SELECT g.id, u.id 
FROM res_groups g, res_users u 
WHERE u.login = 'admin' 
AND g.id NOT IN (
    SELECT gid FROM res_groups_users_rel WHERE uid = u.id
);

Step 2: Force Password Reset Through Configuration

1. Edit your odoo.conf:

ini

admin_passwd = your_new_password
list_db = True

1. Restart Odoo completely:

bash

sudo systemctl restart odoo

Step 3: Direct Session Table Cleanup (If Authentication Still Fails)

sql

-- Clear all active sessions for the admin user
DELETE FROM ir_attachment WHERE res_model = 'ir.sessions';
DELETE FROM ir_sessions WHERE uid = (SELECT id FROM res_users WHERE login = 'admin');

Step 4: Verify User Configuration

Run this diagnostic query:

sql

SELECT 
    u.login, 
    u.active, 
    u.share,
    array_agg(g.name) as groups
FROM res_users u
LEFT JOIN res_groups_users_rel gu ON gu.uid = u.id
LEFT JOIN res_groups g ON g.id = gu.gid
WHERE u.login = 'admin'
GROUP BY u.login, u.active, u.share;

Step 5: Last Resort - Create New Superuser With Full Rights

sql

DO $$
DECLARE
    new_uid integer;
    new_partner_id integer;
BEGIN
    -- Create partner first
    INSERT INTO res_partner (
        name, email, company_id, active, 
        create_uid, create_date, write_uid, write_date
    ) VALUES (
        'Super Admin', 'admin@example.com', 1, true,
        1, now(), 1, now()
    ) RETURNING id INTO new_partner_id;

    -- Create user
    INSERT INTO res_users (
        active, login, password, company_id, partner_id,
        create_uid, create_date, write_uid, write_date
    ) VALUES (
        true, 'superadmin', 'pbkdf2_sha512$600000$ExampleSalt$ExampleHash',
        1, new_partner_id, 1, now(), 1, now()
    ) RETURNING id INTO new_uid;

    -- Grant all groups
    INSERT INTO res_groups_users_rel (gid, uid)
    SELECT id, new_uid FROM res_groups;
END $$;

Critical Checks If Still Not Working:

1. Database Filter: Verify no --db-filter is blocking access
2. Custom Auth Modules: Check installed modules for auth in name
3. Password Policy: Look for password_security module
4. Odoo Version: Confirm exact version with odoo --version

Final Verification:

After making changes:

1. Clear browser cache completely
2. Use incognito mode
3. Try different browser
4. Check Odoo logs for authentication errors:

bash

sudo tail -f /var/log/odoo/odoo-server.log
