user override setting Fully Qualified ID Names for home directory instead of shortnames.
Following an upgrade to QAS Version 126.96.36.19908 if the schema / username-attr-name is set to userprincipalname combined with using the %s setting in user-override to set the home directory to be the name of the user who logs in, the home directory is created in upn format rather then shortname.
Product defect: 453544
The workaround is to change the lowercase %s to be an uppercase %S for example: *:::1::/home/%S:/bin/ksh
The fix is to upgrade to QAS_4_1_0_21790 or higher
