Hi David, I reboot the system after I edit the configure file.

Hi Michael: Did you set the new user's initial password? kinit admin ipa passwd haha Thanks Jenny Also kinit as haha, because haha will be asked to change the password on first authentication. Thanks Jenny I added a new user named /haha(group: ipauser)/ based on the webUI. This user is not a existed system user. Then I added a new Delegations(allow people in group ipauser can modify password for group ipauser) . /[michael@freeipa Desktop]$ su - haha/ /Password: / /Warning: Your password will expire in less than one hour./ /Warning: password has expired./ /Kerberos 5 Password: / /Warning: Your password will expire in less than one hour./ /New UNIX password: / /Retype new UNIX password: / /su: incorrect password/ /[michael@freeipa Desktop]$ su - root/ /Password: / /[root@freeipa ~]# su - haha/ /su: warning: cannot change directory to /home/haha: No such file or directory/ /-sh-3.2$ / Root can su - haha successfully. I think that means the Kerberos works, but new user cannot reset their password in their shell. What should I do? Best Regards, Michael -- Michael Kang（康上明学） There is a giant asleep within every man.
