Hi, I am unable to make mkpasswd/mkgroup to work on a Windows 2003 R2 Enterprise x64. While trying to finish Cygwin config and running mkpasswd -l -d and mkgroup, it fails with the following error: $ mkpasswd -l -u sorins -d /etc/passwd sorins:unused:1012:513:sorins,U-JIRA\sorins,S-1-5-21-1179867521-3364476509-4149538525-1012:/home/sorins:/bin/bash mkpasswd (87): [1212] The format of the specified domain name is invalid. I tried even this option: $ mkpasswd -l /etc/passwd mkpasswd (374): [123] The filename, directory name, or volume label syntax is in correct. JIRA is the computer name and sorins is a Local Administrator This machine is part of domain The question was also posted to: http://serverfault.com/questions/506369/cygwin-mkpasswd-giving-the-format-of-the-specified-domain-name-is-invalid Thanks, Sorin -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
