my xsrvd causes the unable to bind socket error = 13 all the time.

i know when disabling the daemon, the error is gone.
but i am using NSS and I need Netstorage

the rights to the /var/opt/novell/xtier are correct:

drwxrwx--- 3 novlxregd novlxtier 4096 Aug 21 10:09 xregd
drwxrwx--- 2 novlxsrvd novlxtier 4096 Sep 13 12:46 xsrvd

the wwwrun user is member of novlxtier:

esn1:/var/opt/novell/xtier # getent group | grep novlxtier

the UID and the GID are unique

What can i do ???????
