Why might an AD sourced user's group memberships not be imported into Okta?

The situation where an Active Directory (AD) sourced user's group memberships are not imported into Okta can often be attributed to the fact that the administrator did not select all required organizational units. When configuring the integration between Okta and Active Directory, it's essential for the administrator to specify which organizational units (OUs) should be synced. If certain OUs, which contain users or groups, are omitted during the configuration process, the groups associated with those users will not be pulled into Okta. This oversight impacts group membership visibility and availability in Okta, resulting in the user potentially missing out on collaborative features or access that those groups provide.

The other options provide scenarios that are less relevant to the specific task of importing group memberships. For instance, a user having logged into Okta before does not inherently prevent their group memberships from being imported. Additionally, while Okta does have limitations regarding unsupported features, it is designed to work with group memberships from Active Directory if the correct settings are applied. Moreover, saying the groups are not part of the Okta integration would not usually be accurate when the integration is properly configured to include specific OUs. Thus, the selection of organizational units is pivotal to ensuring that all relevant groups are included in the sync process.
