we have a complex infrastructure with WebSEAL, Websphere Portal and a couple of Wesphere AS' where we [obviously] want to set up SSO. we successfully configured TAI++ etc, but unfortunately default LTPA2 token name ("LtpaToken2") is not acceptable for compatibility reasons and we want to change it. Websphere AS 8.5, that we're using, has a special option in "General security -> Single Sign-on" to do so, but that doesn't work however; no matter what we enter, the token issued is still named "LtpaToken2" (well, yes we restarted the AS apparently ;P).
is it something known around websphere community? afaiu this can be customized by implementing a token factory and a token interceptor/validator (i.e. as is suggested here: Generate LTPAToken 2 in custom Web Application), but i'd expect the edit-box that supposedly does so to actually work.
BTW, i take it that renaming LTPA2 tokens is not at all possible in earlier Webspheres?
It is definitely possible since v8. I've tested it on 8.5.5.1 and works fine (I can set ltpa cookie to any name). Verify your settings accessing directly to WAS for example - in admin console, not via TAM. Your problem might be related to WebSEAL and Tai.
I don't quite understand what you mean that ltpatoken2 is not acceptable for compatibility reasons? It was always like that, so changing it will rather introduce incompatibilities, than keeping the default.
