Configuration Variables

The following environment variables are available to tune your configuration (particularly useful with the docker container):

Variable	Value	Default	Purpose
Required Variables
APP_KEY	(value from artisan key:generate)	not defined	This is used to encrypt data used internally. It should only need to be set once for the life of the application. It is in the format of base64:...
APP_URL	http[s]://URL	not defined	The URL used to get to your PLA instance, eg: https://demo.phpldapadmin.org
LDAP_HOST	hostname to your LDAP server	not defined	A resolvable hostname to your LDAP server eg: my.ldap.server.org
Other Optional Variables
APP_TIMEZONE	An applicable timezone	UTC	This timezone used, mostly for, logging. eg: Australia/Melbourne
CACHE_DRIVER	preferred caching driver	file	The driver used for LDAP caching - you can use memcached here. Look at config/cache.php for other possible drivers
LDAP_ALLOW_GUEST	true/false	false	Used to determine if users must login with their own details to use PLA. When true, the tree will be searched using LDAP_USERNAME to search the LDAP server and populate entries[2]
LDAP_CACHE	true/false	false	We use internal caching to reduce the impact to your LDAP server, this enables that caching
LDAP_CONNECTION	string	ldap	config/ldap.php can have definitions for multiple LDAP servers or configurations that use ldaps or starttls. This determines the ldap server configuration to use[3]
LDAP_BASE_DN	Base DN	undefined	Base DN to your LDAP server, if unset, PLA will try to work it out
LDAP_LOGIN_ATTR	LDAP Attribute	uid	Attribute used to login in the login form, if you dont want to use a DN[1]
LDAP_LOGIN_ATTR_DESC	Description of login attribute	User ID	A description to show when LDAP_LOGIN_ATTR is used (in the login box), this is a friendly description
LDAP_LOGIN_OBJECTCLASS	comma delimited list of objectclasses	posixAccount	Objectclass that must be on the user's DN to login. This is a comma delimited list, but any matched objectclass is sufficient to login, eg: posixAccount,inetOrgPerson the user can login if they have posixAccount OR inetOrgPerson [4]
LDAP_NAME	text	LDAP Server	Free form text name for your ldap server, eg: ACME Server
LDAP_PORT	int	389	TCP port used to query ldap server. You may need to change this if your LDAP_CONNECTION refers to a server on a non-standard port, or a SSL enabled port
LDAP_PASSWORD	text	undefined	Password to ldap server[2], eg: mypassword
LDAP_USERNAME	dn	undefined	Authentication DN to connect to ldap server[2], eg: cn=Admin,dc=Test

1 | Your LDAP server LDAP_USERNAME and LDAP_PASSWORD will need to be set - to enable searching the LDAP server to return the DN associated with the LDAP_LOGIN_ATTR. Only one result match must be returned with the query.

2 | Your LDAP server LDAP_USERNAME and LDAP_PASSWORD is mostly used to connect to your LDAP server and obtain the schema (it must have the access to read the schema). If you do use LDAP_ALLOW_GUEST=TRUE, then this LDAP_USERNAME will enable you to browse the LDAP tree and return records that this DN has access to. If LDAP_ALLOW_GUEST=FALSE (the default), then a login box will be presented. When LDAP_LOGIN_ATTR is not DN, then LDAP_USERNAME is used to search the directory to obtain the DN for the attribute value used enable logging into the LDAP server.

3 | PLA comes configured to connect to an LDAP server over an unsecure port ldap, a SSL enabled port ldaps, or with starttls (STARTTLS over an unsecure port). The hostname and port to connect to is configured with LDAP_HOSTNAME/LDAP_PORT respectively for the type of connection you want to use. (In PLA v2.0.0 these values were called openldap/openldaps/openldaptls respectively, but will be changed to ldap/ldaps/starttls in v2.0.1+). See config/ldap.php.

4 | After a DN is retrieved by steps 1/2 above, it is checked to see if it has objectclasses matching LDAP_LOGIN_OBJECTCLASS, and if it does not have any of the objectclasses (if there are more than 1), the user will not be logged in.
