The Name +Service Switch allows user and system information to be obtained from +different databases services such as NIS or DNS\&. The exact behaviour can +be configured throught the \f(CW/etc/nsswitch\&.conf\fP file\&. Users and groups +are allocated as they are resolved to a range of user and group ids +specified by the administrator of the Samba system\&. +.PP +The service provided by \fBwinbindd\fP is called `winbind\' and can be used to +resolve user and group information from a Windows NT server\&. +.PP +The following nsswitch databases are implemented by the \fBwinbindd\fP +service: +.PP +.IP +.IP "passwd" +.IP +User information traditionally stored in the \fBpasswd(5)\fP file and used by +\fBgetpwent(3)\fP functions\&. +.IP +.IP "group" +.IP +Group information traditionally stored in the \fBgroup(5)\fP file and used by +\fBgetgrent(3)\fP functions\&. +.IP +.PP +For example, the following simple configuration in the +\f(CW/etc/nsswitch\&.conf\fP file can be used to initially resolve user and group +information from \f(CW/etc/passwd\fP and \f(CW/etc/group\fP and then from the +Windows NT server\&. +.PP +\f(CWpasswd: files winbind\fP +.PP +\f(CWgroup: files winbind\fP +.PP +.SH "OPTIONS" +.PP +The following options are available to the \fBwinbindd\fP daemon: +.PP +.IP +.IP "\fB-d debuglevel\fP" +Sets the debuglevel to an integer between 0 and 100\&. 0 is for no debugging +and 100 is for reams and reams\&. To submit a bug report to the Samba Team, +use debug level 100 (see \fBBUGS\&.txt\fP)\&. +.IP +.IP "\fB-i\fP" +Tells winbindd to not become a daemon and detach from the current terminal\&. +This option is used by developers when interactive debugging of winbindd is +required\&. +.IP +.PP +.SH "NAME AND ID RESOLUTION" +.PP +Users and groups on a Windows NT server are assigned a relative id (rid) +which is unique for the domain when the user or group is created\&. To +convert the Windows NT user or group into a unix user or group, a mapping +between rids and unix user and group ids is required\&. This is one of the +jobs that \fBwinbindd\fP performs\&. +.PP +As \fBwinbindd\fP users and groups are resolved from a server, user and group +ids are allocated from a specified range\&. This is done on a first come, +first served basis, although all existing users and groups will be mapped +as soon as a client performs a user or group enumeration command\&. The +allocated unix ids are stored in a database file under the Samba lock +directory and will be remembered\&. +.PP +WARNING: The rid to unix id database is the only location where the user +and group mappings are stored by \fBwinbindd\fP\&. If this file is deleted or +corrupted, there is no way for \fBwinbindd\fP to determine which user and +group ids correspond to Windows NT user and group rids\&. +.PP +.SH "CONFIGURATION" +.PP +Configuration of the \fBwinbindd\fP daemon is done through configuration +parameters in the \fBsmb\&.conf\fP file\&. All parameters +should be specified in the [global] section of +\fBsmb\&.conf\fP\&. +.PP +.IP +.IP "winbind uid" +.IP +The winbind uid parameter specifies the range of user ids that are +allocated by the \fBwinbindd\fP daemon\&. This range of +ids should have no existing local or nis users within it as strange +conflicts can occur otherwise\&. +.IP +\fBDefault:\fP +\f(CW winbind uid = \fP +.IP +\fBExample:\fP +\f(CW winbind uid = 10000-20000\fP +.IP +.IP "winbind gid" +.IP +The winbind gid parameter specifies the range of group ids that are +allocated by the \fBwinbindd\fP daemon\&. This range of +group ids should have no existing local or nis groups within it as strange +conflicts can occur otherwise\&. +.IP +\fBDefault:\fP +\f(CW winbind gid = \fP +.IP +\fBExample:\fP +\f(CW winbind gid = 10000-20000\fP +.IP +.IP "winbind cache time" +.IP +This parameter specifies the number of seconds the +\fBwinbindd\fP daemon will cache user and group +information before querying a Windows NT server again\&. +.IP +\fBDefault:\fP +\f(CW winbind cache type = 15\fP +.IP +.IP "template homedir" +.IP +When filling out the user information for a Windows NT user, the +\fBwinbindd\fP daemon uses this parameter to fill in +the home directory for that user\&. If the string \f(CW%D\fP is present it is +substituted with the user\'s Windows NT domain name\&. If the string \f(CW%U\fP +is present it is substituted with the user\'s Windows NT user name\&. +.IP +\fBDefault:\fP +\f(CW template homedir = /home/%D/%U\fP +.IP +.IP "template shell" +.IP +When filling out the user information for a Windows NT user, the +\fBwinbindd\fP daemon uses this parameter to fill in +the home directory for that user\&.
