Thanks for the response and consideration.  I understand the reluctance to add the PCRE dependency.  I would be happy help any way I can in regards to case folding support... provide information and/or testing etc.

I am not sure there is a huge appetite in writing our own module (being part of a bank, they typically frown on rolling/supporting our own) but nonetheless, looks to be an avenue.

Has the Kerberos team considered adding PCRE support to the RULE functionality or have another method to deal with windows/linux integrations (system that is case aware to one that is case aware and sensitive)?  Are there any alternatives/options/other paths we could entertain?

I don't think we'd want to add a dependency on the PCRE library from libkrb5, but I'm open to adding case-folding support in one form or another.  (I'm not immediately sure how it should work in detail.)

One alternative option (in 1.12 or later) is to create, install, and register a localauth module:
