 ticket: new
 subject: NIM: Identity Configuration Panel Fixes
 component: windows

 In the identity configuration panel of Network Identity Manager, the
 user can specify a new identity which can then be configured.

 The existing code didn't check if the identity specified by the user
 already exists.  The patch adds the check.  If the identity already
 exists, the user is notified as such.

 Another bug prevented the user from configuring an identity that was
 added back in following the deletion of the same identity during the
 same session.  The deleted status of the identity was not reset when
 it was added back.

 Additionally, this patch adds code that has already been added to the
 new credentials dialog to apply Windows XP theme textures to the child
 dialogs used as tab panels in the configuration dialog.  Child dialogs
 don't automatically adjust the theme settings based on whether it is
 nested inside a tab control.  The theme must be applied manually.
