What it does

Building Identity Federation With Saml Azure Ad is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Configure SAML 2.0 identity federation between on-premises Active Directory (via AD FS or a third-party IdP) and Microsoft Entra ID, covering federation models (AD FS, password hash sync, pass-through auth, third-party IdP) and the SAML authentication flow. Use when extending on-premises authentication authority to cloud resources or designing hybrid identity SSO architecture for Entra ID.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/api-reference.md` and `references/standards.md`).

It sits in Security, covering Authentication and Red teaming and adversary simulation. It works with Microsoft Entra ID. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.

When your agent uses it

  • Extending on-premises authentication authority to cloud resources
  • Designing hybrid identity SSO architecture for Entra ID

Example prompts

  • “/building-identity-federation-with-saml-azure-ad”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Prepare AD FS Infrastructure
  2. Configure Azure AD Federated Domain
  3. Configure AD FS Claims Rules
  4. Configure Third-Party SaaS Federation
  5. Certificate Lifecycle Management

What it can do on your machine

Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • schemas.xmlsoap.org
    • nexus.microsoftonline-p.com
    • schemas.microsoft.com

    Also links to:

    • learn.microsoft.com
    • docs.oasis-open.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Building Identity Federation With Saml Azure Ad loads about 2.5k tokens when it runs, and up to ~4.4k if it reads all its reference files. Until then it costs about 110 tokens; SKILL.md has 523 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~110
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Building Identity Federation with SAML Azure AD

Overview

Identity federation enables users authenticated by one identity provider to access resources managed by another without maintaining separate credentials. This skill covers establishing SAML 2.0 federation between an organization's on-premises Active Directory (via AD FS or third-party IdP) and Microsoft Entra ID (formerly Azure AD), as well as configuring federated SSO for third-party SaaS applications. Federation eliminates password synchronization concerns and keeps authentication authority on-premises while extending SSO to cloud resources.

When to Use

  • When deploying or configuring building identity federation with saml azure ad capabilities in your environment
  • When establishing security controls aligned to compliance requirements
  • When building or improving security architecture for this domain
  • When conducting security assessments that require this implementation

Prerequisites

  • On-premises Active Directory domain
  • AD FS 2019+ or third-party SAML IdP (Okta, Ping, etc.)
  • Microsoft Entra ID tenant (P1 or P2 license recommended)
  • Azure AD Connect (if using hybrid identity with password hash sync as backup)
  • Public TLS certificate for federation endpoint
  • DNS records for federation service name

Core Concepts

Workflow

Step 1: Prepare AD FS Infrastructure
powershell
# Install AD FS role
Install-WindowsFeature ADFS-Federation -IncludeManagementTools

# Configure AD FS farm
Install-AdfsFarm `
    -CertificateThumbprint $certThumbprint `
    -FederationServiceDisplayName "Corp Federation Service" `
    -FederationServiceName "fs.corp.example.com" `
    -ServiceAccountCredential $gmsaCredential

# Verify AD FS is operational
Get-AdfsProperties | Select-Object HostName, Identifier, FederationPassiveAddress
Step 2: Configure Azure AD Federated Domain
powershell
# Install Microsoft Graph PowerShell module
Install-Module Microsoft.Graph -Scope CurrentUser

# Connect to Microsoft Graph
Connect-MgGraph -Scopes "Domain.ReadWrite.All"

# Convert managed domain to federated
# Using AD FS federation metadata URL
$domainId = "corp.example.com"
$federationConfig = @{
    issuerUri = "http://fs.corp.example.com/adfs/services/trust"
    metadataExchangeUri = "https://fs.corp.example.com/adfs/services/trust/mex"
    passiveSignInUri = "https://fs.corp.example.com/adfs/ls/"
    signOutUri = "https://fs.corp.example.com/adfs/ls/?wa=wsignout1.0"
    signingCertificate = $base64Cert
    preferredAuthenticationProtocol = "saml"
}

# Apply federation settings to domain
New-MgDomainFederationConfiguration -DomainId $domainId -BodyParameter $federationConfig
Step 3: Configure AD FS Claims Rules
powershell
# Add Relying Party Trust for Azure AD
Add-AdfsRelyingPartyTrust `
    -Name "Microsoft Office 365 Identity Platform" `
    -MetadataUrl "https://nexus.microsoftonline-p.com/federationmetadata/2007-06/federationmetadata.xml"

Step 4: Configure Third-Party SaaS Federation

For each SaaS application that supports SAML SSO via Azure AD:

  1. Navigate to Microsoft Entra Admin Center > Enterprise Applications
  2. Add the application from the gallery (or create custom SAML)
  3. Configure Single Sign-On > SAML:
    • Identifier (Entity ID): Application's entity ID
    • Reply URL (ACS): Application's assertion consumer service URL
    • Sign-on URL: Application's login URL
  4. Map user attributes/claims:
    • NameID: user.userprincipalname (email format)
    • Additional claims as required by the application
  5. Download the Federation Metadata XML or certificate
  6. Configure the SaaS app with Azure AD's federation details
Step 5: Certificate Lifecycle Management

AD FS token-signing certificates expire and must be renewed:

powershell
# Check current certificate expiration
Get-AdfsCertificate -CertificateType Token-Signing | Select-Object Thumbprint, NotAfter

# AD FS supports auto-rollover (enabled by default)
Get-AdfsProperties | Select-Object AutoCertificateRollover

# If manual rotation is needed:
# 1. Add new certificate as secondary
Set-AdfsCertificate -CertificateType Token-Signing -Thumbprint $newThumbprint -IsPrimary $false
# 2. Update Azure AD with new certificate
# 3. Promote to primary
Set-AdfsCertificate -CertificateType Token-Signing -Thumbprint $newThumbprint -IsPrimary $true
# 4. Remove old certificate
Remove-AdfsCertificate -CertificateType Token-Signing -Thumbprint $oldThumbprint

Validation Checklist

  • AD FS farm operational with valid TLS and token-signing certificates
  • Azure AD domain configured as federated with correct metadata
  • Claims rules properly transform AD attributes to SAML assertions
  • Test user can authenticate through federation flow end-to-end
  • MFA enforced at AD FS or Azure AD conditional access level
  • Certificate auto-rollover enabled or manual rotation scheduled
  • Federation metadata endpoint publicly accessible
  • Smart lockout configured to prevent brute force
  • Extranet lockout policies configured on AD FS
  • Monitoring configured for AD FS health and certificate expiry
  • Disaster recovery: managed authentication fallback documented
