Hi Martin,
Thanks for the reply, i did try like your self to check out any topics around this subject, but again came up with nothing.
My preference is not to use custom profile names as it could limit your role name (if youare basing the profile name on role name), but i really wanted some hard evidence to present to my peers to get there buy in.
I agree 1380203 does somewhat describe the potential problem although not in the best way. Ill have to convey this message with a hope they will take my advice.
Thanks again !
