Comment 2 Iker Pedrosa 2023-05-25 10:09:59 UTC

I'd like you to clarify one topic with the customer before triaging this bugzilla.

"--with-misc-conv-bufsize" defines the value for PAM_MISC_CONV_BUFSIZE, that is used to read the input string in a PAM conversation (i.e. password input). The PAM_MAX_MSG_SIZE macro mentioned in the bugzilla title is mostly used by pam_echo for printing text messages to the user.

Can you confirm with the customer that their request is related to PAM conversation limits (a.k.a. PAM_MISC_CONV_BUFSIZE)? And not with pam_echo?
