=head1 NAME
smbldap-usermod - Modify a user account
=head1 SYNOPSIS
smbldap-usermod [-c gecos] [-d home_dir] [-r login_name] [-u uid] [-g gid] [-o] [-G group[,...]] [-s shell] [-N first_name] [-S surname] [-P] [-M mail[,...]] [-T mail,[..]] [--shadowExpire date/n] [--shadowMax n] [--shadowMin n] [--shadowInactive n] [--shadowWarning n] [-L] [-U] [-a] [-e expiration_date/n] [--sambaExpire date/n] [-A canchange] [-B mustchange] [-C smbhome] [-D homedrive] [-E scriptpath] [-F profilepath] [-H acctflags] [-I] [-J] [-h] login
=head1 DESCRIPTION
The smbldap-usermod command modifies the system account files to reflect the changes that are specified
on the command line.
=head2 UNIX options
-c, --gecos gecos
The new value of the user's comment field (gecos). (Don't use this to modify displayName or cn. Use -N and -S options combined instead).
-d, --homedir home_dir
The user's new login directory.
-r, --rename new_user
Allow to rename a user. This option will update the dn attribute for the user. You can also update others attributes using the corresponding script options.
-u, --uid uid
The numerical value of the user's ID. This value must be unique, unless the -o option is used. The value must be non negative. Any files which the user owns and which are located in the directory tree rooted at the user's home directory will have the file user ID changed automatically. Files outside of the user's home directory must be altered manually.
-o, --canBeNotUnique
uidNumber can be non unique
-g, --gid initial_group
The group name or number of the user's new initial login group. The group name must exist. A group number must refer to an already existing group. The default group number is 1.
-G, --group [+-]group,[...]
A list of supplementary groups which the user is also a member of. Each group is separated from the next by a comma, with no intervening whitespace. The groups are subject to the same restrictions as the group given with the -g option. If the user is currently a member of a group which is not listed, the user will be removed from the group, unless the '+' or '-' caracter is used to add or remove groups to inital ones.
-s, --shel shell
The name of the user's new login shell. Setting this field to blank causes the system to select the default
login shell.
-N, --givenName
set the user's given name (attribute givenName). Additionally used to set the first name in displayName and cn.
-S, --surname
Set the user's surname (attribute sn). Additionally used to set the last name in displayName and cn.
-P
End by invoking smbldap-passwd to change the user password (both unix and samba passwords)
-M, --mailAddresses mail,[...]
mailAddresses (comma seperated)
-T, --mailToAddress mail,[...]
mailToAddress (forward address) (comma seperated)
--shadowExpire <YYYY-MM-DD/n>
Set the expiration date for the user password. This only affect unix account. The date may be specified as either YYYY-MM-DD or 'n' days from day. The 'n' syntax also supports the extended format (#y)(#m)(#d) for years, months, and days from today. One need not specify all three, so all of the following are examples of valid input: '5y4m2d' (5 years, 4 months, and 2 days), '5y' (5 years), '5y2d' (5 years and 2 days), and '3' (3 days). This option calls the internal 'timelocal' command to set calculate the number of seconds from Junary 1 1970 to the specified date.
--shadowMax <n>
User must change the password, at least, every 'n' days
--shadowMin <n>
User must wait 'n' days once the password has changed before changing it again
--shadowInactive <n>
Number of days of inactivity allowed for the specified user
--shadowWarning <n>
User is warned that the password must be changed four days before the password expires
-L, --shadowLock
Lock unix user's password. This puts a '!' in front of the encrypted password, effectively disabling the password.
-U, --shadowUnlock
Unlock unix user's password. This removes the '!' in front of the encrypted password.
=head2 SAMBA options
-a, --addsambaSAMAccount
Add the sambaSAMAccount objectclass to the specified user account. This allow the user to become a samba user.
-e, --expire <YYYY-MM-DD(HH:MM:SS)/n>
Sets the expiration for both samba (--sambaExpire) and shadow (--shadowExpire).
--ou node
The user's account will be moved to the specified organazional unit. It is relative to the user suffix dn ($usersdn) defined in the configuration file.
Ex: 'ou=admin,ou=all'
--sambaExpire <YYYY-MM-DD HH:MM:SS/n>
Set the expiration date for the user account. This only affects the samba account. The date must be in the following format: YYYY-MM-DD HH:MM:SS. The n-days format of shadowExpire is also supported. This option uses the internal 'timelocal' command to set calculate the number of seconds from Junary 1 1970 to the specified date.
-A, --sambaPwdCanChange
can change password ? 0 if no, 1 if yes
-B, --sambaPwdMustChange
must change password ? 0 if no, 1 if yes
-C, --sambaHomePath path
sambaHomePath (SMB home share, like '\\\\PDC-SRV\\homes')
-D, --sambaHomeDrive drive
sambaHomeDrive (letter associated with home share, like 'H:')
-E, --sambaLogonScript script
sambaLogonScript, relative to the [netlogon] share (DOS script to execute on login, like 'foo.bat')
-F, --sambaProfilePath path
sambaProfilePath (profile directory, like '\\\\PDC-SRV\\profiles\\foo')
-H, --sambaAcctFlags flags
sambaAcctFlags, spaces and trailing bracket are ignored (samba account control bits like '[NDHTUMWSLKI]')
