SAML configuration


SAML authentication is based on the OneloginSamlBundle for Symfony. SuiteCRM provides a base configuration for the bundle. Therefore, most of the configuration will be similar to the one on the OneloginSamlBundle bundle.

For the moment the legacy SAML configurations are not taken into account. Reading legacy configuration will be done as part of future work.


The current implementation does not support IDP initiated logout. Therefore, when logging out the user directly in the IDP, it will not log them out of SuiteCRM and the user would need to be logged out from SuiteCRM manually.

Also, post binding to the logout service is currently not supported.

Known issues

After a session timeout, the user may be re-directed to the native SuiteCRM login, instead of the SAML login. To overcome this, the user needs to clear the cookies and navigate again to the SuiteCRM URL of the specific instance.

This issue will be fixed in a future release.

Enabling SAML authentication

To enable SAML authentication change your .env.local and set:

Configuring env variables

SuiteCRM exposes some of OneloginSamlBundle’s configuration as env variables. The .env file has the default value for all the available variables. When configuring an instance, add the variables you want to override, to .env.local file.

###> SAML CONFIG ###
###< SAML CONFIG ###

Option description


The attribute from SAML to use as the user_name in SuiteCRM. The value received on the SAML request for the defined SAML_USERNAME_ATTRIBUTE needs to match the value on the user_name column of SuiteCRM’s users table.


  • You want to login with user jane.doe

  • The user_name on SuiteCRM’s users table is jane.doe

Then value set on SAML_USERNAME_ATTRIBUTE should be whatever property from the SAML request that provides the username jane.doe.


If the friendly name sent on the SAML request should be used


###> SAML CONFIG ###
###< SAML CONFIG ###

Configuring SAML

As mentioned before, SuiteCRM is using the OneloginSamlBundle bundle. Hence, the configurations used are the same as the ones provided by the bundle.

For detailed information and options check the documentation on:

When adding the configurations to SuiteCRM you should add them to the /extensions/<your-extensions>/config folder. It is a good practice to replicate the same path where the original configuration lives within the core config folder. Thus, a good place to add this configuration is:

  • extensions/<your-extesion>/config/packages/hslavich_onelogin_saml.yaml

    • e.g.: extensions/custom/config/packages/hslavich_onelogin_saml.yaml

Example and option description

The following configuration example was taken from an instance that was using keycloak as an IDP. Some of the IDP example values come from there, that does not mean that all IDPs use similar values.

The comments on the following example provide a description of expected values for some settings.

  # Basic settings

    # entity id of your idp
    entityId: '<idp-entity-id>'  # e.g.: 'http://saml-idp-host/realms/master'

      # single sign on url your IDP
      url: '<idp-sso-url>' # e.g.: 'http://saml-idp-host/realms/master/protocol/saml'
      binding: 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect'

      # single logout service url of your IDP
      url: '<idp-slo-url>' # e.g.: 'http://saml-idp-host/realms/master/protocol/saml'
      binding: 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect'

    # IDP certificate
    x509cert: '<idp-certificate-string> # e.g. 'MIICmzCCAYMCBgGC1LTnr ... ='

  # The SP in this case is your SuiteCRM instance

    # SP entity id. Use your SuiteCRM instance url
    entityId: '<sp-entity-id-use-suitecrm-url> # e.g. 'https://<your-suitecrm-instance>'

      # The path to SuiteCRM's acs service
      url: 'https://<your-suitecrm-instance>/saml/acs'
      binding: 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST'

      # The path to SuiteCRM's SAML logout service
      url: 'https://<your-suitecrm-instance>/saml/logout'
      binding: 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect'

    # SuiteCRM's private key for SAML (sp)
    privateKey: '<sp-private-key>' # e.g. 'MIIEoAIBAAKCAQEAx ...'

    # SuiteCRM's certificate for SAML (sp)
    x509cert: '<sp-cert>' # e.g. 'MIIC1zCCAb8CBgGC1awPM ... ='

  # Optional settings

  # SuiteCRM's base url for SAML
  baseurl: 'https://<your-suitecrm-instance>/saml'

  # NOTE : The values for the following settings will depend on how the IDP is setup
  strict: true
  debug: true
    nameIdEncrypted: false
    authnRequestsSigned: true
    logoutRequestSigned: true
    logoutResponseSigned: false
    wantMessagesSigned: false
    wantAssertionsSigned: false
    wantNameIdEncrypted: false
    requestedAuthnContext: false
    signMetadata: false
    wantXMLValidation: true
    signatureAlgorithm: ''
    digestAlgorithm: ''
      givenName: 'Tech User'
      emailAddress: ''
      givenName: 'Support User'
      emailAddress: ''
      name: 'Example'
      displayname: 'Example'
      url: ''

The above example does not use all the possible options. For information on all the options check the documentation on:

Using Symfony Secrets

One of the great things about using symfony bundles and configuration is that we can take full potential of the features Symfony provides. One of those features is secrets (see the following link to the documentation)

Symfony secrets allows us to safely store sensitive values encrypted in a "vault". Plus these values can also be defined per environment.

In our SAML configuration this could be used to store the certificates and the private keys, which we don’t want to be easily accessible.

To add secrets, first start by following the setup steps on Symfony’s documentation: How to Keep Sensitive Information Secret


After setting up all that is required to add secrets, you can change your SAML config to store some settings in secrets. The following steps will provide an example.

1. Add a secret for your SP private key

Run php bin/console secrets:set SAML_SP_PRIVATE_KEY (the console should show a prompt to set the value)

2. Add a secret for your SP cert

Run php bin/console secrets:set SAML_SP_CERT (the console should show a prompt to set the value)

3. Change hslavich_onelogin_saml.yaml

Lastly change your custom hslavich_onelogin_saml.yaml to use env variables.

The following example is just a snippet of the full file.


  # ...

  # The sp in this case is your SuiteCRM instance


    # SuiteCRM's private key for SAML (sp)
    privateKey: '%env(SAML_SP_PRIVATE_KEY)%'

    # SuiteCRM's certificate for SAML (sp)
    x509cert: '%env(SAML_SP_CERT)%'

    # ...

4. Add other settings to secrets

There are other values that you could add to secrets like the IDP certificate or fingerprint

5. Clear Symfony cache

Alternatives to Symfony Secrets

If you don’t want to use Symfony secrets and would prefer a simpler alternative, it is possible to simply use env variables

Taking the same example used on the Using Symfony Secrets section.


  # ...

  # The sp in this case is your SuiteCRM instance

    # ...

    # SuiteCRM's private key for SAML (sp)
    privateKey: '%env(SAML_SP_PRIVATE_KEY)%'

    # SuiteCRM's certificate for SAML (sp)
    x509cert: '%env(SAML_SP_CERT)%'

    # ...

Using env properties

On the above the SP’s privateKey and x509cert are already pointing to env variables SAML_SP_PRIVATE_KEY and SAML_SP_CERT, respectively.

Instead of using secrets, you could just simply define the values on the .env.local file


# ...


# ...

Don’t forget to clear Symfony cache

Reading env properties from files

It is also possible to read your env properties from files as described on Symfony documentation: env variables.

As an example we are going to change our configuration to read SP x509cert from a file. The following steps describe the changes you need to do.

1. Change config to read from a file

Change your custom hslavich_onelogin_saml.yaml to read the x509cert from a file


  # ...

  # The sp in this case is your SuiteCRM instance

    # ...

    # SuiteCRM's certificate for SAML (sp)
    x509cert: '%env(file:SAML_SP_CERT_FILE)%'

    # ...

2. Define the file in .env.local

On .env.local define the file to read from

# ...


# ...

3. Clear Symfony cache

Allowing fallback to native authentication

SuiteCRM allows to fallback to native authentication using the password set on the SuiteCRM instance for that user.

To use the native logging go to: https://<your-suitecrm-instance>/auth.

After successfully logging in, the user is re-directed to the SuiteCRM’s instance base path, https://<your-suitecrm-instance>/.

Please note that the logout will re-direct you to the SAML login page and not to the SuiteCRM’s native login page.

external_auth_only config

The ability to login into SuiteCRM using the native login will depend on the value for the external_auth_only set on the user’s record:

If a user has external_auth_only set to 1 (or true), the user will not be able to login using the native login.

On the other hand, if a user has external_auth_only set to 0 (or false) the user will be able to attempt to login in, assuming that he has a password set on the SuiteCRM instance.

Configuring user auto creation

By default, user auto creation is disabled for SAML.

When disabled you will only be able to authenticate a user using SAML if you first create them on SuiteCRM.

The auto-create option will auto create the user from SAML if they do not exist on SuiteCRM yet.

Please note that this user will not have any password set on SuiteCRM and the external_auth_only is set to 1 (or true) by default.

To enable SAML user auto creation change your .env.local and set:


When enabling the user auto creation you also need to define how the user information from SAML should be mapped to the user in SuiteCRM

The default configuration for this mapping is defined on config/services/saml/saml.yaml.

To override the configurations you need to copy the file over to the extensions folder on a path like extensions/<your-package>/config/services/saml/saml.yaml


Option description:


Defines how to map the SAML fields to the fields in the user. The keys are the field names in SAML and the values the field names in SuiteCRM. See example on next section.


SAML saml.yaml

File: extensions/<your-package>/config/services/saml/saml.yaml

    email: email1
    'urn:oid:': last_name
    'urn:oid:': first_name

To check the values sent from SAML IDP you can open logs/auth.log, which will have logs from the user creation process. This log is populated when you try to login. So, first try to login with a user that does not exist on the CRM and only then check the logs.

You should find an entry with the message App\Security\Saml\AppSamlUserFactory | createUser attributes. This entry should also contain a json with the attributes that SuiteCRM receives from the IDP.

By having a look at the following snippet from the log you can see that:

  • The last name Doe is sent on an attribute with key urn:oid:

  • The first name Jeremy is sent on an attribute with key urn:oid:

  • The email is sent on an attribute with key email

Exactly like the ones used on the example given before.

[2022-09-15 09:23:53] auth.INFO: App\Security\Saml\AppSamlUserFactory | createUser username: jeremy.doe [] []
[2022-09-15 09:23:53] auth.INFO: App\Security\Saml\AppSamlUserFactory | createUser attributes | {"urn:oid:":["Doe"],"urn:oid:":["Jeremy"],"username":["jeremy.doe"],"email":[""],"Role":["view-profile","offline_access","manage-account","manage-account-links","uma_authorization","default-roles-master"]} [] []

Clear symfony cache

After doing any changes to .env or any config file you need to clear cache.

From your instance root folder run bin/console cache:clear

bin/console cache:clear

If you don’t have access to the terminal you can also delete the contents of: /<path-to-your-project>/cache

  • Please make sure that apache / php has access to write to the cache folder

  • The above is not the legacy cache folder. Do not delete the /<path-to-your-project>/public/legacy/cache
