[PERDITION-USERS] Perdition1.18 problem with LDAP query

Dear all perdition users and experts, I used to have perdition-1.17 work for my mail servers to query for LDAP for mailHost for POP3 and IMAP proxy and normally I will just add a flag in /etc/sysconfig/perdition for POP3 and IMAP and everything will just working fine. Today, I've just setup another mail server (to load balance the mail scanning process and POP/IMAP login) and install with perdition-1.18 (tried also with perdition-1.18rc1), the configuration is the same with my old perdition but I've problem to start the service the error message below. If I remove the (mail=%45s), the service will just start perfect but off course I can't login because ldap will not return anything without the filter. Is there any issue with the new perdition for LDAP query? Looking forward your kind assistance in this matter. Starting perdition services (POP3): /bin/bash: -c: line 0: syntax error near unexpected token `(' /bin/bash: -c: line 0: `ulimit -S -c 0 >/dev/null 2>&1 ; /usr/sbin/perdition.pop3 -m ldap://ldap.abc.com:389/dc=.?uid,mailHost?sub?(mail=%45s)?!BINDNAME=cn=xxx%2cdc=.,X-BINDPW=yyy' Regards -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
