If anyone else wants to try this (I'd guess auth_unix use in mupdate isn't common?)
I use saslauthd for authentication which then uses pam. Is there a way to get rid of auth_unix ?
sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN

is a diff which probably works. I'm still unsure if there are platforms using the 3 argument version of getgrent_r() and it appears to be a non-standard function anyway, so this probably needs configure glue.
This patch breaks imapd and possibly mupdate ( I cant test it )
# telnet localhost 143 * OK ..... server ready 1 login 1 BAD Missing required argument to Login 2 login cyrus dsdsdsd 2 NO Login failed: authentication failure 3 login cyrus abc123 Connection closed by foreign host.
on what would be a successfull login, imapd exits with SIGSEGV
backtrace attached.
