Kerberos clone URL is no longer visible

Summary

We stopped seeing the Kerberos link on the Clone dropdown between versions.

Steps to reproduce

• Enable Kerberos authentication on v11.5.7, see that you still can copy KRB5 clone URL.
• Enable Kerberos on v11.6.5, see that this link no longer appears.

Although the link does not appear, you can still use it to authenticate.

What is the expected correct behavior?
