TL;DR: how do I change the minimum password length requirement for customers created via the SOAP v2 API?
I need to change the minimum password length requirement for customers created via the SOAP V2 API but can't find which file(s) I need to edit. I've tried using grep to check for occurrences of the password length being checked but only found the front-end code for that. It seems like there is some mapping between the SOAP layer and the model layer I'm not aware of, any pointers would be appreciated.
EDIT: So I realised that I was using grep with the case sensitive mode, which was excluding everything, since all the soap files are named
Soap.php. Still looking, though.
