+require (default none).
+The directive may be specified globally and/or per-database.
+.B bind
+requires bind operation prior to directory operations.
+.B LDAPv3
+requires session to be using LDAP version 3.
+.B authc
+requires authentication prior to directory operations.
+.B SASL
+requires SASL authentication prior to directory operations.
+.B strong
+requires strong authentication prior to directory operations.
+Currently
+.B SASL
+and
+.B strong
+conditions are currently same.
+.B none
+may be used to require no conditions (useful for clearly globally
+set conditions within a particular database).
+.TP
+.B sasl-host <fqdn>
+Used to specify the fully qualified domain name used for SASL processing.
+.TP
+.B sasl-realm <realm>
+Specify SASL realm. Default is empty.
+.TP
+.B sasl-regexp <match> <replace>
+Used by the SASL authorization mechanism to convert a SASL authenticated
+username to an LDAP DN. When an authorization request is received, the SASL
+.B USERNAME, REALM,
+and
+.B MECHANISM
+are taken, when available, and combined into a SASL name of the
+form
+.RS
+.RS
+.TP
+.B uid=<UID>[,cn=<REALM>][,cn=<MECH>],cn=AUTHZ
+
+.RE
+This SASL name is then compared against the
+.B match
+regular expression, and if the match is successful, the SASL name is
+replaced with the
+.B replace
+string. If there are wildcard strings in the
+.B match
+regular expression that are enclosed in parenthesis, e.g.
+.RS
+.RS
+.TP
+.B uid=(.*)\\\\+realm=.*
+
+.RE
+.RE
+then the portion of the SASL name that matched the wildcard will be stored
+in the numbered placeholder variable $1. If there are other wildcard strings
+in parenthesis, the matching strings will be in $2, $3, etc. up to $9. The
+placeholders can then be used in the
+.B replace
+string, e.g.
+.RS
+.RS
+.TP
+.B cn=$1,ou=Accounts,dc=$2,dc=$4.
+
+.RE
+.RE
+The replaced SASL name can be either a DN or an LDAP URI. If the latter, the slapd
+server will use the URI to search its own database, and if the search returns
+exactly one entry, the SASL name is replaced by the DN of that entry.
+Multiple
+.B sasl-regexp
+options can be given in the configuration file to allow for multiple matching
+and replacement patterns. The matching patterns are checked in the order they
+appear in the file, stopping at the first successful match.
+.LP
+.B Caution:
+Because the plus sign + is a character recognized by the regular expression engine,
+and it will appear in SASL names that include a REALM, be careful to escape the
+plus sign with a backslash \\+ to remove the character's special meaning.
+.RE
+.TP
+.B sasl-secprops <properties>
+Used to specify Cyrus SASL security properties.
+The
+.B none
+flag (without any other properities) causes the flag properites
+default, "noanonymous,noplain", to be cleared.
+The
+.B noplain
+flag disables mechanisms susceptible to simple passive attacks.
+The
+.B noactive
+flag disables mechanisms susceptible to active attacks.
+The
+.B nodict
+flag disables mechanisms susceptible to passive dictionary attacks.
+The
+.B noanonyous
+flag disables mechanisms which support anonymous login.
+The
+.B forwardsec
+flag require forward secrecy between sessions.
+The
+.B passcred
+require mechanisms which pass client credentials (and allow
+mechanisms which can pass credentials to do so).
+The
+.B minssf=<factor>
+property specifies the minimum acceptable
+.I security strength factor
+as an integer approximate to effective key length used for
+encryption. 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.
+The
+.B maxssf=<factor>
+property specifies the maximum acceptable
+.I security strength factor
+as an integer (see minssf description). The default is INT_MAX.
+The
+.B maxbufsize=<size>
+property specifies the maximum security layer receive buffer
+size allowed. 0 disables security layers. The default is 65536.

+.TP
+.B security <factors>
+Specify a set of factors (separated by white space) to require.
+An integer value is associated with each factor and is roughly
+equivalent of the encryption key length to require. A value
+of 112 is equivalent to 3DES, 128 to Blowfish, etc..
+The directive may be specified globally and/or per-database.
+.B ssf=<n>
+specifies the overall security strength factor.
+.B transport=<n>
+specifies the transport security strength factor.
+.B tls=<n>
+specifies the TLS security strength factor.

+specifies the TLS security strength factor to require for
+directory updates.
+.B update_sasl=<n>
+specifies the SASL security strength factor to require for
+directory updates.
+Note that the
+.B transport
+factor is measure of security provided by the underlying transport,
+e.g. ldapi:// (and eventually IPSEC). It is not normally used.
+.TP
+.B schemacheck { on | off }
+Turn schema checking on or off. The default is on.
.TP
.B sizelimit <integer>
Specify the maximum number of entries to return from a search operation.
The default size limit is 500.

+.TP
.B srvtab <filename>

authenticating clients using kerberos can be found. This option is only
meaningful if you are using Kerberos authentication.

+.B TLSCipherSuite <cipher-suite-spec>
+Permits configuring what ciphers will be accepted and the preference order.
+<cipher-suite-spec> should be a cipher specification for OpenSSL. Example:

+.TP
+.B TLSCertificateFile <filename>
+Specifies the file that contains the
+.B slapd
+server certificate.
+.TP
+.B TLSCertificateKeyFile <filename>
+Specifies the file that contains the
+.B slapd
+server private key that matches the certificate stored in the
+.B TLSCertificateFile
+file. Currently, the private key must not be protected with a password, so
+it is of critical importance that it is protected carefully.
+.TP
+.B TLSRandFile <filename>
+Specifies the file to obtain random bits from when /dev/[u]random
+is not available. Generally set to the name of the EGD/PRNGD socket.
