We are looking to use TA.  Our Uni common authentication system uses Apache/Kerberos.  Is there a way of getting TA to use the Apache-supplied authenticated username?  

The documentation seems to suggest the only options are TA's internal user/pw system (where I saw something that suggests the p/words are held in plain text(!)) or an LDAP server.

Grateful, as always,  for any insight.
