+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-number pagesize
+Set this to a number greater than 0 to request paged results from the

+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-ignore-users-option nss-initgroups-ignoreusers
+This option prevents group membership lookups through LDAP for the

+that value nslcd builds a full list of non-LDAP users on startup.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-number nss-min-uid

+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-number nss-uid-offset
+This option specifies an offset that is added to all LDAP numeric user

+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-number nss-gid-offset

+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-boolean nss-nested-groups
+If this option is set, the member attribute of a group may point to
+another group.  Members of nested groups are also returned in the higher
+level group and parent groups are returned when finding groups for a
+specific user.  The default is not to perform extra searches for nested
+groups.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-boolean nss-getgrent-skipmembers
+If this option is set, the group member list is not retrieved when

+will remain functional so the user will likely still get the correct
+groups assigned on login.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-boolean nss-disable-enumeration
+If this option is set, functions which cause all user/group entries to
+be loaded from the directory will not succeed in doing so.  This can
+dramatically reduce LDAP server load in situations where there are a
+great number of users and/or groups.  This option is not recommended for
+most configurations.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-string validnames
+This option can be used to specify how user and group names are verified
+within the system.  This pattern is used to check all user and group
+names that are requested and returned from LDAP.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-boolean ignorecase
+This specifies whether or not to perform searches using case-insensitive
+matching.  Enabling this could open up the system to authorization
+bypass vulnerabilities and introduce nscd cache poisoning
+vulnerabilities which allow denial of service.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-boolean pam-authc-ppolicy
+This option specifies whether password policy controls are requested and

+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-string pam-authc-search
+By default nslcd performs an LDAP search with the user's credentials
+after BIND (authentication) to ensure that the BIND operation was
+successful.  The default search is a simple check to see if the user's
+DN exists.  A search filter can be specified that will be used instead.
+It should return at least one entry.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-string pam-authz-search
+This option allows flexible fine tuning of the authorisation check that
+should be performed.  The search filter specified is executed and if any
+entries match, access is granted, otherwise access is denied.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} maybe-string pam-password-prohibit-message
+If this option is set password modification using pam_ldap will be
+denied and the specified message will be presented to the user instead.
+The message can be used to direct the user to an alternative means of
+changing their password.
+
+Defaults to @samp{disabled}.
+
+@end deftypevr
+
+@deftypevr {@code{nslcd-configuration} parameter} list pam-services
+List of pam service names for which LDAP authentication should suffice.

+Subject: fix_building_with_latest_versions_of_FFmpeg
+
+Some years-old deprecated stuff has now been removed.
+
+Correct solution is probably to use valid defines etc. in own code, but
+this is more FFMEPG maintainer task (since it also may change how old
+FFMPEG we do support...).

-Subject: [PATCH] tests: don't run buf::oom on 32-bit systems
-
-On a 32-bit Linux systems, the value large enough to make malloc
-guarantee a failure is also large enough that valgrind considers it
-"fishy".  Skip this test on those systems entirely.

+VCR.py records all HTTP interactions that take place through the libraries it
+supports and serializes and writes them to a flat file (in yaml format by
+default).  This flat file is called a cassette.  When the relevant piece of code
+is executed again, VCR.py will read the serialized requests and responses from
+the aforementioned cassette file, and intercept any HTTP requests that it
+recognizes from the original test run and return the responses that corresponded
+to those requests.  This means that the requests will not actually result in
+HTTP traffic, which confers several benefits including:
+@enumerate
+@item The ability to work offline
+@item Completely deterministic tests
+@item Increased test execution speed
+@end enumerate
+If the server you are testing against ever changes its API, all you need to do
+is delete your existing cassette files, and run your tests again.  VCR.py will
+detect the absence of a cassette file and once again record all HTTP
+interactions, which will update them to correspond to the new API.")
