Well, sed command given by bartus11 solved my problem, and any other users in passfile who's password wasn't changed don't disappear.

Here a few lines from passfile (for dovecot auth)

Code:
user1@domain.tld:{SSHA}Hg+be1/EkLn4rmFNy+WFcaF9T2K9yWpv:5000:5000::::
user2@domain.tld:{SSHA}yTTllwdKqbQDyjBUpue9FTvyx+rW5zvx:5000:5000::::
user3@domain.tld:{SSHA}T/a56MosCHi4RFnZEhWC77Cl4EautRMQ:5000:5000::::
user4@domain.tld:{SSHA}mURhtdWsRl5C9/fLxmEu0LuuZ6ocRDrh:5000:5000::::
otheruser1@otherdomain.tld:{SSHA}Ykx2LE+fa2FKzjnctFFC2qFnrk9nvRmW:5000:5000::::
otheruser2@otherdomain.tld:{SSHA}ex67n9fe6BEtniu71xN1JrF4Yna8glLb:5000:5000::::

my script get parameter $1 from command line as user@domain.tld then grep line in passfile for this user password only

Code:
OLDPW=`grep $1 passfile | cut -d: -f2`

so now variable "OLDPW" keeps password only. Then variable "NEWPW" keeps new password generated by `dovecotpw` command, sed do replacement and writes changes do tmpfile, finally `mv` gives me a new passfile with new password for user@domain.tld only.

Anyway, thanks for your tips Smilie

radsqlrelay

RADSQLRELAY(8)						     FreeRADIUS helper program						    RADSQLRELAY(8)

NAME

       radsqlrelay - relay SQL queries to a central database server

SYNOPSIS

       radsqlrelay [-?]  [-d sql_driver] [-b database] [-f file] [-h host] [-u user] [-P port] [-p password] [-1] [-x] file_path

DESCRIPTION

       radsqlrelay  tails a SQL logfile and forwards the queries to a database server. Used to replicate accounting records to one (central) data-
       base, even if the database has extended downtime.

       The SQL logfile is created by the rlm_sql_log module. The module must be configured in the radiusd server before you can use radsqlrelay.

OPTIONS

       -?     Print usage help information.

       -d sql_driver
	      Driver to use: mysql, pg, oracle.

       -b database
	      Name of the database to use.

       -f file
	      Read password from file, instead of command line.

       -h host
	      Connect to host.

       -u user
	      User for login.

       -P port
	      Port number to use for connection.

       -p password
	      Password to use when connecting to server.

       -1     One-shot mode: push the file to database and exit.

       -x     Turn on debugging.

       file_path
	      The pathname of the SQL logfile to use.

NOTES

   Oracle driver
       The command "radsqlrelay -d oracle -b db.domain.tld sql-relay" reads the database description stored in $TNS_ADMIN/tnsnames.ora:

       db.domain.tld =
	 (DESCRIPTION =
	   (ADDRESS_LIST =
	     (ADDRESS = (PROTOCOL = TCP)(HOST = db.domain.tld)(PORT = 1521))
	   )
	   (CONNECT_DATA =
	     (SERVICE_NAME = <DB SID>)
	   )
	 )
