Password recovery

On client the procedure is:
  1. Boot on single-user mode
  2. Change the password on command-line:
 # passwd my_user
 


On XServe the procedure is:
  1. Boot on single-user mode:
  2. Mount partition
 # fsck
 # mount -uw /
  1. Change password
 # nicl -raw /var/db/netinfo/local.nidb -create /users/$newuser _writers_passwd administrator
 # passwd administrator


Create a new user with administrative privileges

First write down the gid which comes from admin group


 # nicl -raw /var/db/netinfo/local.nidb -read /groups/admin
 
Lets say, the gid is '20', then from command line execute:


 # nicl -raw /var/db/netinfo/local.nidb -create /users/my_user
 # nicl -raw /var/db/netinfo/local.nidb -create /users/my_user uid my_user_id
 # nicl -raw /var/db/netinfo/local.nidb -create /users/my_user realname "My User Real Name"
 # nicl -raw /var/db/netinfo/local.nidb -create /users/my_user passwd "my_user_passwd"
 # nicl -raw /var/db/netinfo/local.nidb -create /users/my_user gid 20
 # nicl -raw /var/db/netinfo/local.nidb -create /users/my_user shell "/bin/bash"
 # nicl -raw /var/db/netinfo/local.nidb -create /users/my_user home "/Users/my_user"
 # nicl -raw /var/db/netinfo/local.nidb -create /users/my_user _writers_passwd my_user
 # passwd my_user
 # ditto /System/Library/UserTemplate/English.lproj /Users/my_user
 # chown -R my_user:staff /Users/my_user
 # nicl -raw /var/db/netinfo/local.nidb -read /users/my_user
 # nicl -raw /var/db/netinfo/local.nidb -append /groups/wheel users my_user
 # nicl -raw /var/db/netinfo/local.nidb -append /groups/admin users my_user
