Some platforms, notably eLux RP, uses Heimdal to provide Kerberos libraries and tools.
Our ThinLinc client requires MIT Kerberos5, a fact which sadly isn't mentioned in the TAG.
When trying to log in using a Kerberos ticket, the client fails with:
- a "Kerberos ticket authentication failed" error shown to the user
- an error log that says that libgssapi_krb5.so is nowhere to be found.
See bug 7311 for using alternative kerberos implementations on Windows.
