Using Extended ASCII Character in LAN Manager Names
ID: Q50958
|
The information in this article applies to:
-
Microsoft LAN Manager, versions 1.0, 1.1, 2.0, 2.1, 2.1a, 2.2, 2.2c
on the following platforms: MS-DOS
SUMMARY
This article explains which characters are acceptable in user and group
names in OS/2 LAN Manager. International applications require extended
ASCII characters, and extended character mapping is different for the
Macintosh.
MORE INFORMATION
If you are using API calls such as NetUserAdd() or NetGroupAdd() (or any
API call that accepts a name parameter such as username, groupname,
password, computername, sharename, etc.), you must be sure to convert all
name characters to uppercase letters before making your API call,
including umlauted characters.
You should also note that the NET ADMIN interface does this automatically
for all ASCII characters (including umlauted "u," "a," and "o" characters).
For extended characters that don't have uppercase equivalents (such as
umlauted "e," "i," and variations on these characters), standard uppercase
characters are used. Since the standard C run-time functions do not
support uppercase conversion on extended characters, you must provide
these routines yourself before calling OS/2 LAN Manager APIs.
Also, the Macintosh must conform to the standard IBM ASCII character
set to communicate with OS/2 LAN Manager.
Invalid Characters
The following characters are not valid in an OS/2 LAN Manager name
field such as username, groupname, and password:
ASCII characters 1 - 31 decimal, as well as the following:
. " / \ [ ] : | < > + = ; , ? *
Computernames disallow the period (.), as well as the above characters.
Uppercase Conversion
Standard lowercase ASCII characters a-z are converted to their uppercase
equivalents A-Z. The following is a list of NET ADMIN uppercase
conversions on the following extended ASCII characters:
