Hello,
since kernel 2.6.18-164.el5 no user could login any more from nfs client
into his home directory on nfs server. The kde error message is:
"The following installation problem was detected while trying to start
KDE:
Writing to $HOME directory (/home/<USER>) failed with the
error 'Permission denied'
KDE is unable to start."
/home is exported with nfs4 (gss/krb5), the password is delivered by
nis. Everything works fine if I reboot the nfs server into the previous
kernel 2.6.18-128.7.1.el5. Then it is completely irrelevant which
kernel version the client has. So /home export by nfs4 works for client
with kernel versions 2.6.18-164.el5 and 2.6.18-128.7.1.el5.
If the nfs server runs under kernel 2.6.18-164.el5, the error messages
for the user login process are (names for user, client and domain are
replaced):
