Standard-tooling knowledge (netexec,\n  impacket, certipy, bloodyAD, kerbrute), no vendor-specific engine.\n---\n\n# AD Environment Constraints\n\nCode and commands that work in a lab break in a hardened domain, and the failure almost\nnever says what it is. A Kerberos SPN mismatch surfaces as `invalidCredentials`. NTLM\nbeing disabled surfaces as a logon failure. AES-only KDCs reject your RC4 request with an\netype error you have to know to read. This skill is the checklist of those constraints and\nhow to survive each one with standard tooling.\n\n**Detect the posture before you authenticate.** Every constraint below is detectable up\nfront: probe whether NTLM answers, whether the KDC accepts RC4, whether LDAP signing is\nrequired, whether LDAPS is listening. Fingerprint first, then choose your auth path to\nmatch. Fixing an auth path reactively after each failure is slower and noisier than\nreading the environment once and picking the right transport from the start.\n\n---\n\n## 1. Authentication protocol: NTLM may be disabled\n\nNTLM can be turned off org-wide or on specific DCs by GPO. Any auth path that assumes\nNTLM must fall back to Kerberos.\n\n- impacket: add `-k` (use Kerberos) and `-no-pass` when you have a ccache/TGT.\n- netexec: `-k` / `--kerberos`.\n- certipy: `-k` / add `--dc-host <fqdn>` so it targets the KDC by name.\n\n```bash\n# NTLM path\nnxc smb dc01.corp.local -u user -p pass\n# Kerberos path (NTLM disabled): request a TGT, export ccache, reuse it\ngetTGT.py corp.local/user:pass -dc-ip <dc_ip>\nexport KRB5CCNAME=user.ccache\nnxc smb dc01.corp.local -u user -k --use-kcache\n```\n\n**Reading the signal, not guessing it.** A healthy NTLM-enabled DC answers an NTLM bind\nwith a *bogus* password with exactly `invalidCredentials` / logon-denied, and that proves\nNTLM is alive (the DC reached credential verification and rejected the password). Do not\ninfer \"NTLM disabled\" from a failed bind with a wrong password. NTLM is actually disabled\nonly when you see the SSP collapse markers (`STATUS_NTLM_BLOCKED`, unsupported-function),\nor when a bind fails as logon-denied *while a valid Kerberos TGT for the same identity\nsucceeds concurrently*. Only then is \"wrong password\" ruled out as the cause.\n\nIf a tool only supports pass-the-hash (NTLM hash), treat that as an explicit limitation in\nan NTLM-disabled environment: it will not work, and no flag fixes it.\n\n---\n\n## 2. AES-only KDCs: RC4 blocked by GPO\n\nDomains migrating off legacy crypto enforce AES-128/AES-256 and reject RC4 (arcfour-hmac).\n\n- Do not force `-cipher rc4` or an explicit `etype 23`. A request that only offers RC4\n  fails with `KDC_ERR_ETYPE_NOTSUPP` on an AES-only KDC.\n- Let tools negotiate. impacket and netexec negotiate supported etypes by default.\n- For roasting, offering RC4 *first* is fine where the KDC still allows it (RC4 hashes\n  crack faster); on an AES-only KDC the request simply falls back to AES automatically.\n- On AES-only KDCs with a non-standard salt, AES key derivation needs the salt from an\n  ETYPE-INFO2 pre-auth probe. Standard clients do this as part of the AS exchange; if you\n  hand-roll key derivation you must probe the salt first or the key is wrong.\n\n```bash\n# Kerberoast: RC4 preferred where allowed, auto-falls back to AES on an AES-only KDC\nGetUserSPNs.py corp.local/user:pass -dc-ip <dc_ip> -request -outputfile hashes.kerberoast\n```\n\n---\n\n## 3. LDAP signing, channel binding, and LDAPS\n\nHardened DCs require signed LDAP or channel-bound LDAPS. Plain LDAP on 389 gets rejected\nafter the bind with `strongerAuthRequired` / `LDAP_STRONG_AUTH_REQUIRED`.\n\n- Prefer **LDAPS on 636**. It satisfies both signing and channel binding in one move.\n- Certipy, bloodyAD and any LDAP-writing tool need `-scheme ldaps` (or the equivalent) when\n  channel binding is enforced; a plain LDAP write is refused.\n- If only plain LDAP 389 is available and the server demands signing, the client must sign\n  the connection (SASL sign/seal). A tool with no signing support cannot talk to that DC;\n  that is a hard limitation, document it.\n\n```bash\ncertipy find -u user@corp.local -p pass -dc-ip <dc_ip> -scheme ldaps\nbloodyAD --host dc01.corp.local -d corp.local -u user -p pass --secure get object <target>\n```\n\n**Legacy environments without LDAPS.** Not every domain has a cert on the DC. Where 636 is\nclosed, LDAP 389 is your only channel and it is plaintext; signing is often on to\ncompensate. Distinguish a *transport* failure (636 closed → connection refused / TLS\nhandshake error → retry on 389) from a *policy* failure (bind succeeds, then\n`strongerAuthRequired` → signing/channel-binding issue, a different fix). A tool that tries\nLDAPS and falls back to plain LDAP handles the first case; the second needs signing, not a\nport change.\n\n---\n\n## 4. Clock skew: Kerberos requires ≤5 minutes\n\nKerberos rejects tickets outside a five-minute window with `KRB_AP_ERR_SKEW`. Sync to the\nDC before any Kerberos operation.\n\n```bash\nsudo ntpdate <dc_ip>            # or rdate -n <dc_ip>\n# netexec auto-retries after clock correction on skew errors\n```\n\nIf a TGT request that should work fails with a skew error, it is your clock, not your\ncredentials.\n\n---\n\n## 5. Kerberos SPNs: always FQDN, never short name or IP\n\nThis is the most misleading failure in AD. A service ticket requested for `ldap/dc01`\n(short) or `cifs/10.0.0.1` (IP) does not match the server's canonical SPN, which is the\nFQDN. The KDC cannot find the SPN, or the server rejects the AP-REQ, and the client\nreceives `invalidCredentials` / logon-denied **with no visible Kerberos error**. It looks\nexactly like a bad password when the credentials are perfectly valid.\n\nSymptoms of an SPN mismatch (not a credential problem):\n\n- Unauthenticated posture probes pass; the TGT mints without error.\n- The LDAP/SMB/RDP/WinRM/MSSQL bind over Kerberos fails as logon-denied.\n- No underlying `KRB_AP_ERR_*` in the exception chain.\n\n**Fix:** always target Kerberos by FQDN. Promote short hostnames to FQDN, keep already-formed\nFQDNs (including cross-forest suffixes), and if all you have is an IP you must resolve the\nreal FQDN first; there is no synthetic FQDN that works.\n\n```bash\n# WRONG: Kerberos against a short name or IP\nnxc smb DC01 -u user -k\nnxc smb 10.0.0.1 -u user -k\n\n# RIGHT: full FQDN so the SPN matches\nnxc smb dc01.corp.local -u user -k\n```\n\nAdd the DC to `/etc/hosts` as `<ip> dc01.corp.local dc01` so name resolution never hands a\ntool a short label or an IP where an FQDN is required. Do not assume libraries canonicalize\nthe name via DNS; most do not.\n\n---\n\n## 6. Domain context: authentication domain vs target domain\n\nConfusing these is a top source of cross-domain failure. Keep three things distinct:\n\n| Term | Meaning |\n|---|---|\n| auth domain | the domain the credential belongs to (where the user lives) |\n| target domain | the domain being enumerated or attacked |\n| target DC / PDC | the DC of the target domain |\n\n- Point `-d <target_domain>` at the target, not the auth domain.\n- Cross-domain over a trust: the credential is from domain A, the target is domain B.\n- Cross-domain Kerberos: use the full UPN `user@auth_domain.local` to disambiguate.\n- Cross-domain Kerberoasting: `-target-domain <target_domain>` in impacket / netexec.\n- BloodHound collection: point the collector at the *target* domain's DC.\n\nIn a single-domain lab these coincide, which is exactly why lab-tested commands break in a\nmulti-domain client.\n\n---\n\n## 7. Protected accounts and special objects\n\nDo not assume a technique that works on a normal account works on every account.\n\n- **Protected Users group**: no RC4, no NTLM, no unconstrained delegation. Delegation\n  attacks and RC4 roasting simply do not apply to these members.\n- **LAPS**: the local-admin password is a computer-object attribute (`ms-Mcs-AdmPwd` legacy\n  / `msLAPS-Password`), readable over LDAP only by principals with the delegated right,\n  not a normal credential path.\n- **gMSA**: the password is a managed blob (`msDS-ManagedPassword`) retrievable over LDAP\n  by authorized principals, not something you spray or crack.\n- **AS-REP roasting**: only works against accounts with pre-auth disabled, so verify\n  per-account (`DONT_REQUIRE_PREAUTH`), do not assume the whole domain is roastable.\n- **MachineAccountQuota (MAQ)**: default 10. RBCD and shadow-credential attacks that create\n  a machine account fail when MAQ is 0. Check it before you rely on creating one.\n\n```bash\n# LAPS read (authorized principal), gMSA read, MAQ check: all read-only LDAP\nnxc ldap dc01.corp.local -u user -p pass -M laps\nnxc ldap dc01.corp.local -u user -p pass --gmsa\nnxc ldap dc01.corp.local -u user -p pass -M maq\n```\n\n---\n\n## 8. LDAP paging: the silent truncation\n\nThe DC caps LDAP responses at **1000 objects per page** by default. A query that should\nreturn 50,000 users returns 1,000 and does not warn you. Any query that can return more\nthan a page must use paged search.\n\n- Standard tools (netexec, impacket, bloodyAD, BloodHound collectors) page automatically.\n- If you write a raw LDAP query, use a paged control (`paged_size=1000`) and iterate every\n  page. A single unpaged `search` over users/computers is a guaranteed silent truncation in\n  any real domain.\n\nA truncated collection produces a truncated attack graph, and you never see the path that\nwas in the objects you never fetched.\n\n---\n\n## 9. Network latency: do not tune timeouts to your lab\n\nDevelopers test against a lab on the same subnet: sub-millisecond RTT. Most real\nengagements run over a **VPN** at 100-400 ms RTT, sometimes over 500 ms. AD operations are\nmulti-round-trip, so cost scales with RTT.\n\n| Operation | Round-trips | At 300 ms RTT |\n|---|---|---|\n| TCP + TLS handshake (LDAPS) | ~2-3 | ~0.6-0.9 s |\n| NTLM/SPNEGO bind | ~3 + TLS | ~1.5-2 s |\n| Kerberos AS-REQ / TGS-REQ | ~1 each | ~0.3 s each |\n| DCSync / DRSUAPI | dozens | several s |\n\n- Size timeouts to a latency budget (`worst-case RTT × round-trips + margin`), not to the\n  lab baseline: ~5 s for connect, ~8-10 s for bind, more for heavy RPC, with a hard ceiling\n  so a genuinely dead service still fails in reasonable time.\n- A `TimeoutError` over VPN means \"my budget ran out,\" not \"the DC does not support this.\"\n  Never conclude a constraint (disabled/required) from a timeout; that is a wrong-answer\n  cached from a slow link.\n- Before widening timeouts, confirm the slowness is the network and not a blocked local\n  event loop. If connect measures milliseconds but the high-level operation takes seconds on\n  a fast link, the problem is your code, not latency.\n\n---\n\n## Applying this checklist\n\nMatch the constraints to what you are doing:\n\n- Anything that authenticates or opens a transport → §§ 1-7.\n- Anything that queries many objects → § 8.\n- Anything over a remote link → § 9.\n\nDesign for the hardest environment on every axis at once: AES-only, no LDAPS, NTLM\ndisabled, cross-domain, tens of thousands of objects, high latency. Tooling that survives\nthat also runs against a lab. The reverse is not true.\n","tagline":"Real-world Active Directory environment constraints that silently break attacks when ignored: NTLM disabled (Kerberos fallback), AES-only KDCs (RC4 blocked by GPO), LDAP signing and channel binding requiring LDAPS on 636, Kerberos clock skew (KRB_AP_ERR_SKEW), SPNs that must be F","category":"research","tags":["agent-skill"],"author":"ADScanPro","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"ADScanPro/Claude-AD","creatorName":"ADScanPro","creatorUrl":"https://github.com/ADScanPro","sourceUrl":"https://github.com/ADScanPro/Claude-AD/tree/main/skills/ad-environment-constraints","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/adscanpro-ad-environment-constraints#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
