2.3.1.80. nsslapd-nagle
When the value of this attribute is off, the TCP_NODELAY option is set so that LDAP responses (such
as entries or result messages) are sent back to a client immediately. When the attribute is turned
on, default TCP behavior applies; specifically, sending data is delayed so that additional data can be
grouped into one packet of the underlying network MTU size, typically 1500 bytes for Ethernet.
Parameter Description
Entry DN cn=config
Valid Values on | off
Default Value off
Syntax DirectoryString
Example nsslapd-nagle: off
2.3.1.81. nsslapd-outbound-ldap-io-timeout
This attribute limits the I/O wait time for all outbound LDAP connections. The default is 300000
milliseconds (5 minutes). A value of 0 means that the server does not impose a limit on I/O wait time.
Parameter Description
Entry DN cn=config
Valid Range 0 to the maximum 32-bit integer value
(2147483647)
Default Value 300000
Syntax DirectoryString
Example nsslapd-outbound-ldap-io-timeout: 300000
2.3.1.82. nsslapd-plug-in
This read-only attribute lists the DNs of the plug-in entries for the syntax and matching rule plug-ins
loaded by the server.
2.3.1.83. nsslapd-port (Port Number)
This attribute gives the TCP/IP port number used for standard LDAP communications. To run SSL/TLS
over this port, use the Start TLS extended operation. This selected port must be unique on the host
system; make sure no other application is attempting to use the same port number. Specifying a port
number of less than 1024 means the Directory Server has to be started as root.
The server sets its uid to the nsslapd-localuser value after startup. When changing the port
number for a configuration directory, the corresponding server instance entry in the configuration
directory must be updated.
The server has to be restarted for the port number change to be taken into account.
Parameter Description
Entry DN cn=config
Valid Range 1 to 65535
