Solaris 10 'su' failed

Question

I've installed a new Solaris 10 as the development platform. And I added the some packages from www.sunfreeware.com.
Then, I found user could not use the 'su' command.
Here is the dmesg.

Answer 1

after installing sol 10_72 su worked.
then i needed to re-install the directory server. from that moment on i had exactly the same problem as you have.
if i configure the runtime library env like this:
crle -c /var/ld/ld.config -l /lib:/usr/lib:/usr/lib/mps
(using the paths ldd shows),
su works again
