Enable Kerberos Authentication in the Domain

Enable Kerberos on a gateway node within the domain.

Run the infasetup switchToKerberosMode command on a gateway node within the domain to change the authentication to Kerberos network authentication.

Shut down the domain and all Informatica services. Shut down the services in the following order:

Metadata Manager Service

PowerCenter® Integration Service

PowerCenter® Repository Service

Content Management Service

Analyst Service

Data Integration Service

Model Repository Service

At the command prompt on a gateway node, switch to the directory where the infasetup executable is located:

<Informatica installation directory>\isp\bin

Run the following command:

infasetup switchToKerberosMode -ad <administrator name> -srn <Kerberos realm names> -urn <Kerberos realm names> -spnSL <service principal level>

The following table describes the options and arguments for the infasetup switchToKerberosMode command:

Option	Argument	Description
-administratorName -ad	user_name	User name for the domain administrator account that is created when you configure Kerberos authentication. Specify the name of an account that exists in Active Directory. After you configure Kerberos authentication, this user is included in the `_infaInternalNamespace` security domain that the command creates. If the domain uses a single Kerberos realm to authenticate users, specify the samAccount name of the account you want to use as the administrator account. If the domain uses Kerberos cross realm authentication, specify the fully qualified user principal name of the account you want to use as the administrator account, including the realm name. For example: sysadmin@COMPANY.COM
-ServiceRealmName -srn	Kerberos_realm_name	Name of the Kerberos realm that the domain uses to authenticate users. The realm name must be in uppercase and is case-sensitive. To configure Kerberos cross realm authentication, specify the name of each Kerberos realm that the domain uses to authenticate users, separated by a comma. For example: COMPANY.COM,EAST.COMPANY.COM,WEST.COMPANY.COM Use an asterisk as a wildcard character before a realm name to include all realms that include the name. For example: *EAST.COMPANY.COM
-UserRealmName -urn	Kerberos_realm_name	Name of the Kerberos realm that the domain uses to authenticate users. The realm name must be in uppercase and is case-sensitive. To configure Kerberos cross realm authentication, specify the name of each Kerberos realm that the domain uses to authenticate users, separated by a comma. For example: COMPANY.COM,EAST.COMPANY.COM,WEST.COMPANY.COM Use an asterisk as a wildcard character before a realm name to include all realms that include the name. For example: *EAST.COMPANY.COM
-SPNShareLevel -spnSL	NODE\|PROCESS	Service principal level for the domain. Set to NODE to enable Kerberos at the node level. Set to PROCESS to enable Kerberos at the process level.

The following example changes the domain authentication to Kerberos and sets the sysadmin user account as the administrator account in a domain that uses a single Kerberos realm to authenticate users:

infasetup switchToKerberosMode -ad sysadmin -srn COMPANY.COM -urn COMPANY.COM –spnSL NODE

The following example changes the domain authentication to Kerberos and sets the sysadmin user account as the administrator account in a domain that uses Kerberos cross realm authentication:

infasetup switchToKerberosMode -ad sysadmin@COMPANY.COM -srn COMPANY.COM,COMPANY.EAST.COM,COMPANY.WEST.COM -urn COMPANY.COM,COMPANY.EAST.COM,COMPANY.WEST.COM –spnSL NODE
