User Authentication

User Authentication

During installation, you can select the authentication to use for the Informatica domain.
The Informatica domain can use the following types of authentication to authenticate users in the Informatica domain:
  • Native user authentication
  • LDAP user authentication
  • Kerberos network authentication
Native user accounts are stored in the Informatica domain and can only be used within the Informatica domain. Kerberos and LDAP user accounts are stored in an LDAP directory service and are shared by applications within the enterprise.
If you enable Kerberos authentication during installation, you must configure the Informatica domain to work with the Kerberos key distribution center (KDC). You must create the service principal names (SPN) required by the Informatica domain in the Kerberos principal database. The Kerberos principal database can be an LDAP directory service. You must also create keytab files for the SPNs and store it in the Informatica directory as required by the Informatica domain.
If you do not enable Kerberos authentication during installation, the installer configures the Informatica domain to use native authentication. After installation, you can set up a connection to an LDAP server and configure the Informatica domain to use LDAP authentication in addition to native authentication.
