I'm a bit confused because <MYREALM> in the error message is the correct realm. I altered the idmapd.conf (server and client). Just be be sure we speak about the same things: <MYREALM>: MYSERVERHOSTNAME.SUB1.DOMAIN.TLD server: myserverhostname.sub1.domain.tld client: myclienthostname.sub2.sub1.domain.tld /etc/idmapd.conf Domain = myserverhostname.sub1.domain.tld Local-Realm = MYSERVERHOSTNAME.SUB1.DOMAIN.TLD > # The following should be set to the local NFSv4 domain name > # The default is the host's DNS domain name. > #Domain = local.domain.edu I wondered if a "local domain name" should include the hostname or not, thus I tried sub1.domain.tld and also myserverhostname.sub1.domain.tld The later worked and let the error message disappear from the log. The rest is the same and mount still hangs. regards knut server log: Feb 13 10:23:29 tm rpc.svcgssd[18043]: leaving poll Feb 13 10:23:29 tm rpc.svcgssd[18043]: handling null request Feb 13 10:23:29 tm rpc.svcgssd[18043]: sname = root/<client-fqdn>@<MYREALM> Feb 13 10:23:29 tm rpc.svcgssd[18043]: DEBUG: serialize_krb5_ctx: lucid version!
