Previously, the nucn-stans framework was enabled by default in Directory Server, but the framework is not stable. As a consequence, deadlocks and file descriptor leaks could occur. This update changes the default value of the nsslapd-enable-nunc-stans parameter to "off". As a result, Directory Server is now stable.

Comment 5 Viktor Ashirov 2018-08-28 12:35:39 UTC
Build tested: 389-ds-base-

On a fresh instance:
[root@server ds]# ldapsearch -xLLL -D cn=Directory\ Manager -w password -b cn=config -s base nsslapd-enable-nunc-stans
dn: cn=config
nsslapd-enable-nunc-stans: off

[root@server ds]# pstack $(pidof ns-slapd) | grep 'nunc-stans\|ns_' -c

Nunc-stans is disabled by default, marking as VERIFIED.
