From the command line try:
For a lot of reasons it is a really, really bad idea to try to exceed this value:
applications using (_POSIX_)LOGIN_NAME_MAX for usernames will segfault.
LDAP will not work.
Other PAM schemes will not work.
OpenSSH protocol 1 will fail with overlong usernames.
/etc/rhosts won't work for users on your box connecting to remote boxes
I don't think anything good will come from this but try editing /etc/default/login.defs.
CentOS follows Red Hat useradd conventions, see: /etc/default/useradd
I have been told that my college wants to implement LDAP. This creates a problem for me because my users active directory names and email user names differ from their unix system logins.

Hello,
In shared memory, when using shmget function, first parameter is ket_t key.
I know it is an integer type, but length of it is system dependent. That means may not be have integer's ranges.
What is range of key_t in Linux? Is it different in distros, for example in ubuntu & fedora? (2 Replies)

sasl_server_userdb_checkpass_t - Plaintext Password Verification Callback
SYNOPSIS
#include <sasl/sasl.h>
int sasl_canon_user_t(sasl_conn_t *conn,
void *context,
const char *user, unsigned ulen,
unsigned flags,
const char *user_realm,
char *out_user, unsigned out_umax,
unsigned *out_ulen)
DESCRIPTION
sasl_canon_user_t Is the callback for an application-supplied user canonicalization function. This function is subject to the requirements
that all user canonicalization functions are: It must copy the result into the output buffers, but the output buffers and the input buffers
may be the same.
context context from the callback record
user and ulen Un-canonicalized username (and length)
flags Either SASL_CU_AUTHID (indicating the authentication ID is being canonicalized) or SASL_CU_AUTHZID (indicating the authorization ID
is to be canonicalized) or a bitwise OR of the the two.
user_realm Realm of authentication.
out_user and out_umax and out_ulen The output buffer, max length, and actual length for the username.
RETURN VALUE
SASL callback functions should return SASL return codes. See sasl.h for a complete list. SASL_OK indicates success.
