That's by design. "whoami" uses geteuid which retrieves the user identity from the numerical id.
You should use who am I instead which retrieves the user identity from the utmpx/wtmpx or similar source:
Code:
# id
uid=0(root) gid=0(root)
# whoami
root
# who am I

wtmpx

utmpx(4)							   File Formats 							  utmpx(4)

NAME

       utmpx, wtmpx - utmpx and wtmpx database entry formats

SYNOPSIS

       #include <utmpx.h>
       /var/adm/utmpx
       /var/adm/wtmpx

DESCRIPTION

       The utmpx and wtmpx files are extended database files that have superseded the obsolete utmp and wtmp database files.

       The  utmpx database contains user access and accounting information for commands such as who(1), write(1), and login(1). The wtmpx database
       contains the history of user access and accounting information for the  utmpx database.

USAGE

       Applications should not access these databases directly, but should use the functions described on the getutxent(3C) manual page to  inter-
       act with the utmpx and wtmpx databases to ensure that they are maintained consistently.

FILES

       /var/adm/utmpx	       user access and adminstration information

       /var/adm/wtmpx	       history of user access and adminstrative information

SEE ALSO

       getutxent(3C), wait(3C)wait.h(3HEAD)
