# Pentesting FreeIPA
## When to Use
- You find Unix/Linux hosts integrated with a central identity provider, a FreeIPA web UI on `443`, or `/etc/krb5.conf` and `/etc/ipa/default.conf` on a foothold.
- LDAP (`389`/`636`) and Kerberos (`88`) services answer on a server and clients have `sssd` configured.
- You compromised a domain-joined Unix host and want to enumerate users/hosts/groups, harvest Kerberos tickets, and abuse HBAC/sudo rules for lateral movement.
- You hold a standard user, a host keytab, or a service account and need a graph-driven path to domain compromise.
## Critical: Techniques Most Often Missed
- **Anonymous LDAP bind** — by default FreeIPA's LDAP allows anonymous binds, exposing a large amount of data unauthenticated.
```bash
ldapsearch -x # anonymous bind, dumps enumerable data unauthenticated
```
- How to CONFIRM: `ldapsearch -x -b "dc=domain,dc=local"` returns user/host entries without credentials.
