I don't have a problem with dot "." in usernames. The version of shadow-utils is shadow-utils-4.0.3-40 though. at "@" doesn't work for me either, but than I am not so sure it should. # rpm -q shadow-utils shadow-utils-4.0.3-40 # useradd other.test "." is ok now for "@" i agree. it was possible in rhl 7.3 (and other unbelievable combinations) but i am not sure if it should really work. if "@" is not ok in usernames ( shrek-m@gmx.net ) than this bug can be closed. thanks as per release 38 changelog, "@" is not ok in usernames: - conform to posix for user/group name input checking [def 3.426 and 3.189] which is posix portable filename character set [3.276] while disallowing dash for first char as recommended, and disallow dollar sign) only "[A-Za-z0-9._][A-Za-z0-9._-]*" is allowed (with a special exception made for samba machine names, by option, in release 41 and above) On IEEE Std 1003.1-2017 standard available at https://ieeexplore.ieee.org/document/8277153/ And also on IEEE Std 1003.1-2001 available at http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap06.html#tag_06_01 You should use the 6.1 Portable Character Set that includes some special characters (see section 3.426 User Name) |
