NFS4 home directory is not mounted with ksu

[Amir Saad]

I could successfully install Kerberos, OpenLDAP on my network; I
changed the login and SSH to use the Kerberos tickets and this works
correctly. Home directories are mounted successfully upon login,
however; when ksu to another user I get 'Permission Denied' and I
cannot access any home directory. Here is my log:

Jan 8 10:23:30 machine1 rpc.gssd[17142]: ERROR: GSS-API: error in
gss_acquire_cred(): Miscellaneous failure - Unknown code krb5 195

Jan 8 10:23:30 machine1 rpc.gssd[17142]: WARNING: Failed to create krb5
context for user with uid 1001 for server nfs-server-machine

Jan 8 10:23:30 machine1 rpc.gssd[17142]: ERROR: GSS-API: error in
gss_acquire_cred(): Miscellaneous failure - Unknown code krb5 195

Jan 8 10:23:30 machine1 rpc.gssd[17142]: WARNING: Failed to create krb5
context for user with uid 1001 for server nfs-server-machine


My platform:
Debian 4, MIT Kerberos 5.

Please note that NFS4 is mounted successfully upon login, the problems happens only with ksu.


Any help?



Thank you
