snowleopard.jpgMy last post looked at an issue where network users without a proper path assigned to their home directory in WorkGroup Manager would be unable to properly create a local home folder. This post looks at an issue with login failures that can arise with mobile network accounts under Snow Leopard Server. If you have mobile network accounts – AD or LDAP – that cannot login, jump to the bottom of this post for the fix.

After creating several network user accounts under Snow Leopard, I found that my test user account was unable to login. But instead of the standard shake of the login window that indicates a failed login attempt, the login window actually began to collapse as if the login process was starting – the login & password boxes disappeared briefly before reappearing suddenly & displaying the familiar shake to indicate that login had failed.

Interestingly, the user account could still be used to access system services without issue. Attempting to login to AFP shares or setup iCal for shared calendaring using the users login credentials worked fine.

Several reboots & rebinds later I dug through the system log to find the following error: error = Error Domain=NSOSStatusErrorDomain Code=-35 “Operation could not be completed. (OSStatus error -35.)” (no such volume).

Turns out the was unable to create the mobile account at login. The solution was to create it manually. On the client computer, login as an administrator & run the following two commands as root:

sudo /System/Library/CoreServices/ -n username

sudo createhomedir -c -u username

This forces the creation of both the mobile user account & their home directory. Log out & log in with your mobile user’s credentials – you should be able to login without issue. This should work for both Active Directory and Open Directory mobile user accounts.

Thanks to Rich Trouton of the macenterprise google group for posting the fix!

As of this writing, Snow Leopard Server is at version 10.6.1

snowleopard.jpgUPDATE: Due to some errors on my part, I have had to heavily edit this article. The information contained herein is now accurate. Sorry for the confusion!

I recently ran into a bit of an irritating issue while setting up directory services on a new server running Snow Leopard Server (10.6.1). It seems that as of 10.6, users without a value for their home directory (NFSHomeDirectory) are unable to create a home directory on managed clients. I had created a series of users and assigned them to groups. Every time I would log in to test, however, error messages would appear warning about problems creating the user’s home directory.

What is interesting, however, is that users can still access system services (AFP, iCal, etc) without issue. Attempting to login to AFP shares using the users login credentials works fine. Attempting to login to a managed client, however, generates a warning message about being unable to locate the users home directory. When logged in, the user cannot create new files or folders on the desktop – the whole system behaves as if the user has no permissions for the desktop.

A quick look at the logs on the server hinted that the issue was tied to home directories, with several warning messages about problems with home directories: CFPreferences: user home directory at /99 is unavailable. User domains will be volatile.

Sure enough, when I looked in WGM, I had forgotten to assign home directories to the accounts. I quickly corrected this (relatively large) oversight & BAM! clients were logging in without issue!

This is a fairly sharp departure from previous behavior. Prior to Snow Leopard, network users with no home directory assigned (NFSHomeDirectory=99) could still login; their home directories were simply created in a folder named “99” in the root of the boot volume (/99/user1). As of 10.6 this behavior seems to have changed. Why exactly, I’m not yet sure – although I imagine it must be tied to security.

My next post explores an issue where mobile account creation can sometime fail on login. Stay tuned!

As of this writing, Snow Leopard Server is at version 10.6.1.

Snow Leopard Cheat-sheet

August 31, 2009

SnowLeopardLast Friday, Apple released OS X 10.6, “Snow Leopard” to the general public. There’s been quite a bit of excitement building around it’s release, although unlike the media & PR hype surrounding the release of Leopard, this time around the buzz seems a little more organic, building more through blogs, consultants, techs, & users instead of corporate PR departments.

While I haven’t yet done extensive testing of Snow Leopard’s newest features & enhancements (I spent the days following it’s release in the mountains of Garibaldi Provincial Park), I did make some time to put together a quick ‘cheat-sheet’ of key features, enhancements, & system requirements for the new OS. Be sure to stay-tuned, however. There’s sure to be more Snow Leopard posts to follow…
