Hi Kos, maybe I found the underlaying problem!!! # Connection policy: # persist: DSA connections are kept open (default) # oneshot: DSA connections destroyed after request +nss_connect_policy oneshot -#nss_connect_policy persist I set 'nss_connect_policy' to oneshot and Cyrus IMAP starts without problems (so far - I'll run further test) !!! I saw in the ldap.log that if I did a 'ls -all' over a directory the ldap chat terminated (successfully - but nonetheless) with the following lines_ Mar 12 13:34:50 roka2 slapd[2942]: conn=449 op=4 SEARCH RESULT tag=101 err=0 nentries=1 text= Mar 12 13:34:50 roka2 slapd[2942]: conn=449 fd=42 closed (connection lost) I changed to and the chat ended with the following lines: Mar 12 13:52:50 roka2 slapd[2942]: conn=511 op=1 SEARCH RESULT tag=101 err=0 nentries=1 text= Mar 12 13:52:50 roka2 slapd[2942]: conn=511 op=2 UNBIND Mar 12 13:52:50 roka2 slapd[2942]: conn=511 fd=42 closed Where when I did a ldapsearch uid=whateveraccount it terminated with the following lines: Mar 12 13:55:53 roka2 slapd[2942]: conn=521 op=1 SEARCH RESULT tag=101 err=0 nentries=1 text= Mar 12 13:55:53 roka2 slapd[2942]: conn=521 op=2 UNBIND Mar 12 13:55:53 roka2 slapd[2942]: conn=521 fd=44 closed I was irritated by 'closed (connection lost)'. 'Connection lost' does not look like a clean termination of a communication.

Since I have no problem on amd64, but on x86 it exists. yours, kos Respectfully, Konstantin V.
