+`LDAP_USER_ATTRIBUTES`
+: The attribute or attributes to retrieve from the LDAP directory for users
+  when they log in, with multiple attributes separated by commas. If specified,
+  the attributes listed are retrieved from each authenticated users and
+  dynamically applied to the parameters of that user's connections as

 `LDAP_CONFIG_BASE_DN`
 : The base of the DN for all Guacamole configurations. If omitted, the
   configurations of Guacamole connections will simply not be queried from the
   LDAP directory, and you will need to store them elsewhere, such as within a
   MySQL or PostgreSQL database.
 
+`LDAP_DEREFERENCE_ALIASES`
+: Controls whether or not the LDAP connection follows (dereferences) aliases
+  as it searches the tree. Possible values for this property are "never"
+  (the default), so that aliases will never be followed, "searching", to
+  dereference during the search operations after the base object is located,
+  "finding", to dereference in order to locate the search base but not during
+  the actual search, and "always", to always dereference aliases.
+
+`LDAP_FOLLOW_REFERRALS`
+: This option controls whether or not the LDAP module follows referrals when
+  processing search results. Referrals can be pointers to another part of the
+  current LDAP tree, or to a completely different tree altogether, hosted on
+  a different server and/or port. Valid options are "false" (the default),
+  which means that referrals will be ignored, or "true", where the client

+
+`LDAP_MAX_REFERRAL_HOPS`
+: When LDAP referrals are enabled, this option controls how many hops the
+  LDAP client will follow before refusing to continue. The default is 5.
+
+`LDAP_MAX_SEARCH_RESULTS`
+: The maximum number of search results that can be returned by a single LDAP
+  query. LDAP queries which exceed this number of results may fail. By default
+  the maximum number of results for a single LDAP query is 1000.

+`LDAP_OPERATION_TIMEOUT`
+: The timeout, in seconds, of any single LDAP operation, after which the
+  operation will be aborted. The default is 30 seconds.

 As documented in [](ldap-auth), Guacamole does support combining LDAP with a
 MySQL or PostgreSQL database, and this can be configured with the Guacamole
 Docker image, as well. Each of these authentication mechanisms is independently
