Great !

For my understanding
sed -i "/${line}/ s/^/# /" $F_NAME ==> in file $F_NAME search for occurence of $line and then look at the first position for # and replace it by a space ?

and
sed -i "/${line}/ s/# *//" $F_NAME ==> in file $F_NAME search for occurence of $line and then look somewhere for a space followed by everything and replace it by a # ?

That mean that the space should be not at the 1st position of the line ?

Anyway in my case that do the job.

Thank you very much

idmap_tdb

IDMAP_TDB(8)															      IDMAP_TDB(8)

NAME

       idmap_tdb - Samba's idmap_tdb Backend for Winbind

DESCRIPTION

       The  idmap_tdb  plugin  is  the default backend used by winbindd for storing SID/uid/gid mapping tables and implements both the "idmap" and
       "idmap alloc" APIs.

IDMAP OPTIONS

       range = low - high
	  Defines the available matching uid and gid range for which the backend is authoritative. Note that the range commonly matches the  allo-
	  cation range due to the fact that the same backend will store and retrieve SID/uid/gid mapping entries. If the parameter is absent, Win-
	  bind fail over to use the "idmap uid" and "idmap gid" options from smb.conf.

IDMAP ALLOC OPTIONS

       range = low - high
	  Defines the available matching uid and gid range from which winbindd can allocate for users and groups. If the parameter is absent, Win-
	  bind fail over to use the "idmap uid" and "idmap gid" options from smb.conf.

EXAMPLES

       The following example is equivalent to the pre-3.0.25 default idmap configuration using the "idmap backend = tdb" setting.

	    [global]
		idmap domains = ALLDOMAINS
		idmap config ALLDOMAINS:default = yes
		idmap config ALLDOMAINS:backend = tdb
		idmap config ALLDOMAINS:range	= 10000 - 50000

		idmap alloc backend = tdb
		idmap alloc config:range = 10000 - 50000

       The  original  Samba  software  and  related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.
