Learn about bugs fixed in Directory Server 11.7 that have a significant impact on users.
The ns-slapd
binary is now linked with the thread-safe libldap_r
library, no longer causing segmentation fault
An upstream change in the build system introduced a regression by linking the ns-slapd
binary with the non thread-safe libldap
library instead of the thread-safe libldap_r
. Consequently, the ns-slapd
process could fail with a segmentation fault. This update fixes the problem with the build system code and the ns-slapd
binary is now linked back with the thread-safe libldap_r
library. As a result, the segmentation fault no longer occurs.

Directory Server now flushes the entry cache less frequently
Previously, Directory Server flushed its entry cache even when it was not necessary. As a result, in certain situations, Directory Server was unresponsive and had bad performance. With this update, Directory Server flushes the entry cache only when it is necessary.

4.3. Known issues
Learn about known problems and, if applicable, workarounds in Directory Server 11.7.
Access log displays an error message during Directory Server installation in FIPS mode
When you install Directory Server in the FIPS mode, the access log file displays the following error message:
[time_stamp] - WARN - slapd_do_all_nss_ssl_init - ERROR: TLS is not enabled, and the machine is in FIPS mode. Some functionality won’t work correctly (for example, users with PBKDF2_SHA256 password scheme won’t be able to log in). It’s highly advisable to enable TLS on this instance.
Such behavior happens because at first, Directory Server finds that TLS is not initialized and logs the error message. However, later when the dscreate
utility completes TLS initialization and enables security, the error message is no longer present.
(BZ#2153668)
Directory Server settings that are changed outside the web console’s window are not automatically visible
Because of the design of the Directory Server module in the Red Hat Enterprise Linux 8 web console, the web console does not automatically display the latest settings if a user changes the configuration outside of the console’s window. For example, if you change the configuration using the command line while the web console is open, the new settings are not automatically updated in the web console. This applies also if you change the configuration using the web console on a different computer. To work around the problem, manually refresh the web console in the browser if the configuration has been changed outside the console’s window.

Configuring a referral for a suffix fails in Directory Server
If you set a back-end referral in Directory Server, setting the state of the backend using the dsconf <instance_name> backend suffix set --state referral
command fails with the following error:
Error: 103 - 9 - 53 - Server is unwilling to perform - [] - need to set nsslapd-referral before moving to referral state
As a consequence, configuring a referral for suffixes fail. To work around the problem:
Set the
nsslapd-referral
parameter manually:# ldapmodify -D "cn=Directory Manager" -W -H ldap://server.example.com dn: cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config changetype: modify add: nsslapd-referral nsslapd-referral: ldap://remote_server:389/dc=example,dc=com
Set the back-end state:
# dsconf <instance_name> backend suffix set --state referral
As a result, with the workaround, you can configure a referral for a suffix.
(BZ#2063033)
Directory Server replication fails after changing password of the replication manager account
After a password change, Directory Server does not properly update the password cache for the replication agreement. As a consequence, when you change the password for the replication manager account, the replication breaks. To work around this problem, restart the Directory Server instance. As a result, the cache is rebuilt at start-up, and the replication connection binds with the new password instead of the old one.
