This file is required\&. Absence of this file will not prevent system operation, but will probably result in undesirable operation\&. .PP This file is a readable text file, each line of the file describing one configuration parameter\&. The lines consist of a configuration name and value, separated by whitespace\&. Blank lines and comment lines are ignored\&. Comments are introduced with a "#" pound sign and the pound sign must be the first non\-white character of the line\&. .PP Parameter values may be of four types: strings, booleans, numbers, and long numbers\&. A string is comprised of any printable characters\&. A boolean should be either the value \fIyes\fR or \fIno\fR\&. An undefined boolean parameter or one with a value other than these will be given a \fIno\fR value\&. Numbers (both regular and long) may be either decimal values, octal values (precede the value with \fI0\fR) or hexadecimal values (precede the value with \fI0x\fR)\&. The maximum value of the regular and long numeric parameters is machine\-dependent\&. .PP 提供如下配置项： .PP \fBPASS_MAX_DAYS\fR, \fBPASS_MIN_DAYS\fR and \fBPASS_WARN_AGE\fR are only used at the time of account creation\&. Any changes to these settings won\*(Aqt affect existing accounts\&. .SH "交叉引用" .PP 如下交叉引用显示影子密码套件哪个程序使用哪个参数。 .PP chfn .RS 4 CHFN_RESTRICT .RE .PP chgpasswd .RS 4 ENCRYPT_METHOD MAX_MEMBERS_PER_GROUP MD5_CRYPT_ENAB SHA_CRYPT_MAX_ROUNDS SHA_CRYPT_MIN_ROUNDS .RE .PP chpasswd .RS 4 SHA_CRYPT_MAX_ROUNDS SHA_CRYPT_MIN_ROUNDS .RE .PP gpasswd .RS 4 ENCRYPT_METHOD MAX_MEMBERS_PER_GROUP MD5_CRYPT_ENAB SHA_CRYPT_MAX_ROUNDS SHA_CRYPT_MIN_ROUNDS .RE .PP groupadd .RS 4 GID_MAX GID_MIN MAX_MEMBERS_PER_GROUP SYS_GID_MAX SYS_GID_MIN .RE .PP groupdel .RS 4 MAX_MEMBERS_PER_GROUP .RE .PP groupmems .RS 4 MAX_MEMBERS_PER_GROUP .RE .PP groupmod .RS 4 MAX_MEMBERS_PER_GROUP .RE .PP grpck .RS 4 MAX_MEMBERS_PER_GROUP .RE .PP grpconv .RS 4 MAX_MEMBERS_PER_GROUP .RE .PP grpunconv .RS 4 MAX_MEMBERS_PER_GROUP .RE .PP lastlog .RS 4 LASTLOG_UID_MAX .RE .PP login .RS 4 CONSOLE_GROUPS DEFAULT_HOME ERASECHAR FAIL_DELAY FAKE_SHELL HUSHLOGIN_FILE KILLCHAR LOGIN_RETRIES LOGIN_TIMEOUT LOG_OK_LOGINS LOG_UNKFAIL_ENAB TTYGROUP TTYPERM TTYTYPE_FILE USERGROUPS_ENAB .RE .PP newgrp / sg .RS 4 SYSLOG_SG_ENAB .RE .PP newusers .RS 4 ENCRYPT_METHOD GID_MAX GID_MIN MAX_MEMBERS_PER_GROUP MD5_CRYPT_ENAB HOME_MODE PASS_MAX_DAYS PASS_MIN_DAYS PASS_WARN_AGE SHA_CRYPT_MAX_ROUNDS SHA_CRYPT_MIN_ROUNDS SUB_GID_COUNT SUB_GID_MAX SUB_GID_MIN SUB_UID_COUNT SUB_UID_MAX SUB_UID_MIN SYS_GID_MAX SYS_GID_MIN SYS_UID_MAX SYS_UID_MIN UID_MAX UID_MIN UMASK .RE .PP pwck .RS 4 PASS_MAX_DAYS PASS_MIN_DAYS PASS_WARN_AGE .RE .PP pwconv .RS 4 PASS_MAX_DAYS PASS_MIN_DAYS PASS_WARN_AGE .RE .PP su .RS 4 CONSOLE_GROUPS DEFAULT_HOME ENV_PATH ENV_SUPATH SULOG_FILE SU_NAME SYSLOG_SU_ENAB .RE .PP sulogin .RS 4 ENV_HZ .RE .PP useradd .RS 4 CREATE_HOME GID_MAX GID_MIN HOME_MODE LASTLOG_UID_MAX MAIL_DIR MAX_MEMBERS_PER_GROUP PASS_MAX_DAYS PASS_MIN_DAYS PASS_WARN_AGE SUB_GID_COUNT SUB_GID_MAX SUB_GID_MIN SUB_UID_COUNT SUB_UID_MAX SUB_UID_MIN SYS_GID_MAX SYS_GID_MIN SYS_UID_MAX SYS_UID_MIN UID_MAX UID_MIN UMASK .RE .PP userdel .RS 4 MAIL_DIR MAIL_FILE MAX_MEMBERS_PER_GROUP USERDEL_CMD USERGROUPS_ENAB .RE .PP usermod .RS 4 LASTLOG_UID_MAX MAIL_DIR MAIL_FILE MAX_MEMBERS_PER_GROUP .RE .SH "缺陷" .PP Much of the functionality that used to be provided by the shadow password suite is now handled by PAM\&. Thus, /etc/login\&.defs is no longer used by \fBpasswd\fR(1), or less used by \fBlogin\fR(1), and \fBsu\fR(1)\&. Please refer to the corresponding PAM configuration files instead\&. .SH "参见" .PP \fBlogin\fR(1), \fBpasswd\fR(1), \fBsu\fR(1), \fBpasswd\fR(5), \fBshadow\fR(5), \fBpam\fR(8)\&.
