Hi Gents. I have a user with UID of 57500500 and Samba's clients would fail with: NT_STATUS_NO_IMPERSONATION_TOKEN while trying to connect/authenticate. There was not idrange in the domain for that ID )so I created one: ...   Range name: CCN.PRIVATE_id_range   First Posix ID of the range: 57400000   Number of IDs in the range: 9999   First RID of the corresponding RID range: 57400000   First RID of the secondary RID range: 57409999   Range type: local domain range and -> $ ipa-replica-manage dnarange-show drunk.in.ccn: 57400000-57409999 sucker.in.ccn: 1600700501-160079999 but I still cannot samba-connect to the service/server, still fails with the same error. Would you know what is wrong and/or what I'm missing - all thoughts share are much appreciated. many thanks, L.
