Should not be an issue. Really depends on the client.
But cDOT can handle larger UIDs.
Example:
# id hi uid=100062(hi) gid=512(domain admins) groups=512(domain admins)
::*> diag secd authentication translate -node node1 -vserver SVM -unix-user-name hi 100062
# su hi sh-4.1$ cd /unix sh-4.1$ touch uidfile sh-4.1$ ls -lan | grep uidfile -rw-rw-r--. 1 100062 512 0 Jun 24 2015 uidfile

Perhaps a slightly daft question, but I can't find the answer rummaging. Someone's just asked if there's a problem with going past 16 bit UIDs (>65535).
Is anyone able to point me in the right direction?
