The problem is simply a limit on the number of args one config line can
The fix is straightforward: increase the
#define MAXARGS 100
in $LDAPROOT/ldap/servers/slapd/config.c
to a more reasonable number and recompile slapd.
Remeber that a multi-line entry with lines other than the first beginning with

a space or tab are treated as a single, long line in order to allow very long
in the conf file.
