finally! I got the solution few days back from the support. My NIS users have first letter in uppercase!, normalization is already enabled for AD users and somehow it is not enabled for NIS users. The below command has normalized the NIS users & groups, after this point the usermapper rules started working. isi auth nis modify --normalize-groups=1 --normalize-users=1
Hi All,  I have NIS & AD configured in my isilon, for the multi-protocol environment I am trying the change the AD user primary group from "domain users" to that of the primary group from his/her unix account. So the usermapper rule for this is '*\* += * [group]', but this is not working. The AD user access token is still showing "domain users" as the primary group. Where as if I create a rule specific to any single user like '*\user01 += user01 [group]' it is working just as expected.  Has anyone experienced this issue? If so how was it resolved?  Regards, Abhilash.
