The slapd.conf(5)/slapd-config(5) man pages contain this wording for the
sasl-secprops keyword:

0  (zero)  implies  no  protection, 1 implies integrity protection only, 56
allows DES or other weak  ciphers, 112  allows triple DES and other strong
ciphers, 128 allows RC4, Blowfish and other modern strong ciphers.   The 
default  is  0.


I think it's been quite a while since RC4 was considered a "modern strong
cipher".
