kerberos sso brakes ticket auth on REST-API

[hi-ko]

In a kerberos enabled Alfresco (tested in CE 6.1, 7.1) login ticket based authentication (either by header or url parameter) works if sso is disabled and no longer works on the REST-API endpoint (/alfresco/api/) if sso is enabled. The webscript enpoint (/alfresco/service/) still works as expected appending url parameter alf_ticket:

Once sso is enabled ticket authentication fails on REST-API and I don't see any code in the stacktrace trying to login by ticket. Instead I only see attempts to use the ticket as username.

kerberos.authentication.sso.enabled=true
kerberos.authentication.browser.ticketLogons=true

Full stacktrace (username is heiko, Ticket starts with TI*:
catalina.out.txt

testcase is enable kerberos sso and access REST-API with ticket as described in the docs: Using the ticket

+1 Already present in 7.3

This is a bug in the alfresco code. Is there some plan to correct this ?
