Full_Name: Emmanuel L.charny Version: 2.4.40 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (80.12.43.27) The slapd-config man page contains a slightly incorrect explaination for the olcLogLevel config element. One can read : olcLogLevel: <integer> [...] ... The desired log level can be input as ... or as a list of the names that are shown between brackets... but the sample does not show any bracket being used : olcLogLevel: acl trace Actually, using brackets does not work (you can't inject the attribute using [acl trace] or {acl trace})
