from my notes- Subject: Re: Case #: Citrix FAS with Imprivata
Hi.
This morning I ran through a test of using the same keytab file in two seperate Imprivata Enterprises. The ktpass command had to be used, and not the ISXKerbUtil tool.
The steps taken were: -
1. Create Keytab file
Firstly, on a Windows Server in the same domain as the appliances check if an account already exists with the SPN, type the following:
• setspn -q host/ssohost4kerberos.domain.xxx
Next, on the same server delete the SPN as part of your troubleshooting, type the following:
• setspn -d host/ssohost4kerberos.domain.xxx SSOKerberos
Again on the same server use the ktpass command to create the keytab
• ktpass -mapuser
SSOKerberos@domain.xxx -pass XXXXXXX -princ host/
ssohost4kerberos.domain.xxx@DOMAIN.XXX -out OneSign.keytab -ptype KRB5_NT_PRINCIPAL -crypto ALL
These Windows commands are very case sensitive. See the attached "Error Creating and Uploading keytab File" document for further details.
2. Upload Keytab
In the Imprivata Admin Console on both Enterprises navigate to Users > Directories, select the domain. Then delete any pre-existing keytab files and upload and apply the new keytab file.
Then I followed the remaining instructions of the attached "Configuring Kerberos Authentication.pdf" document.
• Step 5: Verify that the Keytab File Uploaded to the Appliance
• Step 6: Configure a Computer Policy for Kerberos Authentication
• Step 7: Disable the Imprivata OneSign Login Module
• Step 8: Enable the Imprivata Credential Manager Module
