login problem using cyrus-sasl-2.1.18 and cyrus-imapd-2.2.6

[victor]

I try to detail the problem(I have some more information):

The error:
Jul 8 10:46:03 mail68 imap[24978]: cannot connect to saslauthd server: 
No such file or directory

What I have tryed to debug the problem:
1) imapd.conf contains a line : "saslauthd_path:/var/state/saslauthd"

2) Saslauthd is running and I have the directory /var/state/saslauthd 
with a file mux in it.

3) When I try the command: "echo 1 > /var/state/saslauthd/mux", the error is
     bash: /var/state/saslauthd/mux: No such device or address

4) When I start cyrus I have a error(I don't know if is related with the 
insuccesfull login):
master[28489]: setrlimit: Unable to set file descriptors limit to -1: 
Operation not permitted

5) When I do "strace /usr/cyrus/bin/master -f -v" the output is:
