I have a SP site which is setup to authenticate with an external two-way trust domain. I've used the stsadm tool to configure the people-picker to browse this domain and add users/groups to this site. For the most part authentication works fine but have a select few (not disabled) which just can't login. The check permissions tool says that have the desired relevant access but the login prompt just keeps re-appearing.
Here's where it gets stranger. Sometimes my own trusted domain account takes three attempts to login before this is accepted whereas others are allowed in straight away!
Are there any logs for troubleshooting login at all? I'm struggling to find these.
What could be the problem? I'd be happier if this just didn't work across the board to make troubleshooting a bit easier but then this job would be easy wouldn't it ;)
Any advice much appreciated.
