Step 3: Setting up Bitbucket user profile attributes

    We will be setting up user profile attributes for Bitbucket. If your users are stored in a directory that is Read Only, please check Disable Attribute Mapping in User Profile tab and follow steps given in Matching a User.

    bitbucket sso-11

    a. Finding correct attributes
  • Go to Configure IDP tab. Scroll down and click on Test Configuration.
  • You will see all the values returned by your IDP to Bitbucket in a table. If you don't see value for First Name, Last Name, Email or Username, make the required settings in your IDP to return this information.
  • Once you see all the values in Test Configuration, keep the window open and go to User Profile tab.
    • b. Setting profile attributes
  • In this tab, fill the values by matching the name of the attribute. For instance, if the Attribute Name in the Test Configuration window is NameID, enter NameID against Username
  • Setting up both Username and Email is required if you want to let users register. If you want existing users to the only login, configure the attribute using which you will match the user in Bitbucket.
    • c. Matching a User
    When the user logs into Bitbucket, one of the user's data/attribute coming in from the IDP is used to search the user in Bitbucket. This is used to detect the user in Bitbucket and log in the user to the same account.
  • Go to User Profile tab
  • Select Username or Email for Login/Search Bitbucket user account by
  • Enter the attribute name from IDP which corresponds to Username or Email using Finding Correct Attributes

Step 4: Assigning groups to users

    We will be setting up user group attributes for Bitbucket. If your users are stored in a directory that is Read Only, please check Disable Group Mapping in User Groups tab and skip to Setting default group.

    bitbucket sso-12
    a. Finding Group Attribute
  • Just like we found Attribute Name for User Profile attributes, we find group attribute.
  • Go to Configure IDP tab. Scroll down and click on Test Configuration.
  • You will see all the values returned by your IDP to Bitbucket in a table. If you don't see value with groups, make the required settings in your IDP to return group names.
  • Once you see all the values in Test Configuration, keep the window open and go to User Groups tab.
  • Enter the Attribute Name of group against Group Attribute
  • At the bottom of the page, all groups in Bitbucket are shown. You can map groups in IDP which correspond to Bitbucket groups. For example, if you want all users in dev-ops and dev groups in IDP to be added to crucible-users, you will need to enter dev-ops;dev against crucible-users
  • If you want user mapping to work for only limited groups in Bitbucket, check the option Update User Groups

    • b. Setting default group
  • Select the users' Default Group in the tab User Groups. If no group is mapped, users are added by default to this group.
  • You can enable default groups for all users or only new users using the option Enable Default Groups for.

Step 5: SSO Settings

    The settings in SSO Settings tab define the user experience for Single Sign On.
    a. Sign In Settings
  • Set button text for button on login page using Login Button Text
  • Set redirect URL after login using Relay State. Keep this empty for coming back to the same page user started from
  • Enable Auto-redirect to IDP if you want to allow users to login only using IDP. Enable backdoor for emergency
    • bitbucket sso-13
    b. Sign Out Settings
    Set Logout URL or Logout Template to redirect users after logout action.

    bitbucket sso-14
    c. SSO Error Settings
    Set error template to redirect users to a custom error page instead of login page. Use this if you have Auto-redirect to IDP enabled.
