I think that note is precisely referring to the NFS specific accounts I already mentioned.
Otherwise, unless you use a really old (>13 years) Solaris release, there should be no problem using large UIDs.

nfs3_do_readdirplus
nfs3_do_readdirplus(5) File Formats Manual nfs3_do_readdirplus(5)
NAME
nfs3_do_readdirplus - turn on or off NFS version 3 readdirplus functionality on the NFS server
VALUES
Failsafe
Default
Allowed values
DESCRIPTION
controls the ability to turn on or off the NFS version 3 readdirplus functionality on the NFS server. If this functionality is turned off,
the client is forced to use the readdir functionality instead.
Who Is Expected to Change This Tunable?
The distributed file system administrator should examine this value if performance issues are being experienced when reading large directo-
ries.
Restrictions on Changing
The tunable is dynamic; tuning will take effect immediately on the running system.
What Are the Side Effects of Turning Off the Readdirplus Functionality?
By forcing the client to use readdir instead of readdirplus, the client is no longer following the NFS version 3 protocol. If problems
occur, turn back on.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of
HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
