SLAPO-HOMEDIR(5) File Formats Manual SLAPO-HOMEDIR(5)
slapo-homedir - Home directory provisioning overlay
ETCDIR/slapd.conf
The homedir overlay causes slapd(8) to notice changes involving
RFC-2307bis style user-objects and make appropriate changes to
the local filesystem. This can be performed on both master and
replica systems, so it is possible to perform remote home
directory provisioning.
Both slapd.conf and back-config style configuration is supported.
overlay homedir
This directive adds the homedir overlay to the current
database, or to the frontend, if used before any database
instantiation; see slapd.conf(5) for details.
homedir-skeleton-path <pathname>
olcSkeletonPath: pathname
These options set the path to the skeleton account
directory. (Generally, /etc/skel) Files in this directory
will be copied into newly created home directories.
Copying is recursive and handles symlinks and fifos, but
will skip most specials.
homedir-min-uidnumber <user id number>
olcMinimumUidNumber: number
These options configure the minimum userid to use in any
home directory attempt. This is a basic safety measure to
prevent accidentally using system accounts. See
REPLICATION for more flexible options for selecting
accounts.
homedir-regexp <regexp> <path>
olcHomedirRegexp: regexp path
These options configure a set of regular expressions to
use for matching and optionally remapping incoming
homeDirectory attribute values to pathnames on the local
filesystem. $number expansion is supported to access
values captured in parentheses.
For example, to accept any directory starting with home
and use it verbatim on the local filesystem:
homedir-regexp ^(/home/[-_/a-z0-9]+)$ $1
To match the same set of directories, but create them
instead under exporthome, as is popular on Solaris NFS
servers:
homedir-regexp ^(/home/[-_/a-z0-9]+)$ /export$1
homedir-delete-style style
olcHomedirDeleteStyle: style
These options configure how deletes of posixAccount
entries or their attributes are handled; valid styles are
IGNORE, which does nothing, and DELETE, which immediately
performs a recursive delete on the home directory, and
ARCHIVE, which archives the home directory contents in a
TAR file for later examination. The default is IGNORE.
Use with caution. ARCHIVE requires homedir-archive-path
to be set, or it functions similar to IGNORE.
homedir-archive-path <pathname>
olcHomedirArchivePath: pathname
These options specify the destination path for TAR files
created by the ARCHIVE delete style.
The homedir overlay can operate on either master or replica
systems with no changes. See slapd.conf(5) or slapd-config(5)
for more information on configure syncrepl.
Partial replication (e.g. with filters) is especially useful for
providing different provisioning options to different sets of
users.
The following LDIF could be used to add this overlay to cn=config
(adjust to suit)
dn: cn=module{0},cn=config
changetype: modify
add: olcModuleLoad
olcModuleLoad: homedir
dn: olcOverlay=homedir,olcDatabase={1}mdb,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcHomedirConfig
olcOverlay: homedir
olcSkeletonPath: /etc/skel
olcMinimumUidNumber: 1000
olcHomedirRegexp: ^(/home/[-_/a-z0-9]+)$ /export/$1
olcHomedirDeleteStyle: ARCHIVE
olcHomedirArchivePath: /archive
DELETE, MOD, and MODRDN operations that remove the unix
attributes when delete style is set to DELETE will recursively
delete the (regex modified) home directory from the disk. Please
be careful when deleting or changing values.
MOD and MODRDN will correctly respond to homeDirectory changes
and perform a non-destructive rename() operation on the
filesystem, but this does not correctly retry with a recursive
copy when moving between filesystems.
The recursive copy/delete/chown/tar functions are not aware of
ACLs, extended attributes, forks, sparse files, or hard links.
Block and character device archival is non-portable, but should
not be an issue in home directories, hopefully.
Copying and archiving may not support files larger than 2GiB on
some architectures. Bare POSIX UStar archives cannot support
internal files larger than 8GiB. The current tar generator does
not attempt to resolve uid/gid into symbolic names.
No attempt is made to try to mkdir() the parent directories
needed for a given home directory or archive path.
ETCDIR/slapd.conf
default slapd configuration file
/etc/skel (or similar)
source of new homedir files.
