/etc/profile is marked as config file though, so rpm will not replace it if it has been modified when updating the package (not even when using “zypper dup”… 
).
So check whether you have an /etc/profile.rpmnew file and rename that to /etc/profile.
Or delete your /etc/profile and force a reinstallation of aaa_base to get the original file.
zypper in -f aaa_base
