Bug description:
Environment: IPA + NFSv4 (sec=krb5).
nss.c uses wrong '@' sign to detect the NFS domain resulting in
"nobody" ownerships and the following error messages in an IPA
environment:
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: key: 0x2c254c26 type: uid value: rns at localdomain@ipa.localdomain timeout 600
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: calling nsswitch->name_to_uid
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nss_getpwnam: name 'rns at localdomain@ipa.localdomain' domain 'ipa.localdomain': resulting localname '(null)'
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nss_getpwnam: name 'rns at localdomain@ipa.localdomain' does not map into domain 'ipa.localdomain'
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: nsswitch->name_to_uid returned -22
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: final return value is -22
Affects at least libnfsidmap2=0.25-5 and 0.25-5.1 on 16.04, 16.10,
17.04, 17.10
