[ldap/servers/slapd/back-ldbm/dblayer.c:5294]: (warning) scanf without field width limits can crash with huge input data.

Source code is

sscanf(thisline,"%[a-z]%c%s",attribute,&delimiter,value);

but

char value[128], delimiter;

Maybe

sscanf(thisline,"%[a-z]%c%128s",attribute,&delimiter,value);

would be better code.
