Manage mapping from hosts to principals for an nfs client.
/usr/sbin/nfshostmap -a hostname alias1 alias2 | -d hostname | -e hostname alias1 alias2 | -l
All hosts defined as aliases will be mapped to the host defined as a hostname when constructing a kerberos request to the server. This is useful if, for example, a server has interfaces wizard.sub.austin.ibm.com and wizard.austin.ibm.com; if this server's kerberos principal is wizard.austin.ibm.com, nfshostmap -a wizard.austin.ibm.com wizard.sub.austin.ibm.com run on the client will take care of this problem.
This modifies /etc/nfs/princmap, which is read by the gssd daemon on startup.
