Keytab files

If you are using SRP authentication, keytab files are useful when running unattended automation scripts that make use of Network Shell proxy services or make calls to the BLCLI. Keytab files provide the blcred utility with long-term user credentials that can be used to authenticate a user.

For single sign-on, BMC Server Automation only supports a keytab file for SRP authentication. The SRP keytab file is called user_info.dat. For instructions about setting up user_info.dat, see Generating a user information file.

Note that BMC Server Automation also employs a keytab file for its AD/Kerberos implementation. Procedures for the AD/Kerberos implementation explain the use of a keytab file in that context.

Because of their sensitive nature, access to keytab files should be tightly controlled.
