[Serusers] problem with special user for SER running

[Grigory Fishilevich]

Hi, 

i install SER 0.8.14 on my SUSE Linux Enterprise Server 9. 
it works. but i dont like to run SER under root-account, so 
i add a new system user "ser", i can start SER, but serctl have problems 
with access to fifo. After "serctl moni" i see in /var/log/messages 
following: 

Apr 20 09:31:57 xxx /sbin/ser[8669]: ERROR: open_reply_pipe: open
error (/tmp/ser_receiver_8732): Permission denied
Apr 20 09:31:57 xxx /sbin/ser[8669]: ERROR: fifo_reply: no reply pipe
/tmp/ser_receiver_8732

the user "ser" is member of group "users". 
how can i allow the user "ser" to create and access the fifos? 

many thanks,

Grigory Fishilevich
