Long logins OD/AD…

[HobbesSOC]

We are experiencing a very strange occurrence in one of our Mac labs.

It seems that groups of our students get a “stuck” login window. The login button turns gray after they click it, and then it just sits there forever.

All of these students share one thing in common, a “firstname.lastname” user name format.

The problem does not seem to occur with our other users who are using a “firstname lastname” user name format.

The environment is an AD/OD setup, with the macs authenticating against AD and using OD to get preferences etc.

The server(s) logs don’t say much, but I have not enabled directory service debugging yet.

AD users on PC clients with the firstname.lastname user name format have no issue logging in.

Are there any caveats for using a firstname.lastname format for the username on the OD end of things?

Just chiming in here, because my MacBook Pro users have extenuating login times with AD (no OD) and some have first.lastname accounts. Although legacy users were set up like “jdoe” and new users are first.lastname, I’ve seen this occur in both user formats.

I have perused the varied posts/responses re: “slow login times”, and most point to DNS records (some to active network connections).

My users have Mobile AD accounts (initially bound from OS X 10.4.6), so credentials are cached and out of office login times are (mostly) bearable. This seems like a matter of changing the default time out for login lookups? I remember seeing a post about changing this setting somewhere (could have sworn it was AFP548)–anyone else?

To follow up; the posting I was recalling is from Philip Rinehart over at MacEnterprise.org.

He’s posted a Python script to change the default timeouts, but you might be able to use the defaults command, too.
