Bug#604891: (rpc.gssd: Failed to create machine krb5 context with any credentials cache)

2010-11-28 Thread Friedemann Stoyan
It seems the issue is solved.

Due to a bad BIOS-Setup (dynamic clock ticks) the time slow down. NTP wasn't
be able to correct this. After fixing this the observed misbehavior vanished.

The Bug can be closes. Sorry for the noise.

Bug#604891: rpc.gssd: Failed to create machine krb5 context with any credentials cache

2010-11-24 Thread Friedemann Stoyan
Package: nfs-common
Version: 1:1.2.2-4
Severity: normal

I mount a NFS4-Share with krb5p and automounter. After some time the client 
refuses
the mount. The rpc.gssd complains:

rpc.gssd[12224]: in authgss_create()
rpc.gssd[12224]: in authgss_refresh()

rpc.gssd[10927]: WARNING: Failed to create machine krb5 context with any 
credentials cache for server reliant.lab.swapon.de

Which is not true:

$ sudo klist -c /tmp/krb5cc_machine_LAB.SWAPON.DE
Credentials cache: FILE:/tmp/krb5cc_machine_LAB.SWAPON.DE

Nov 24 20:18:54  Nov 25 20:13:54  nfs/reliant.lab.swapon...@lab.swapon.de

When I restart the rpc.gssd, everything works well again.
