### This configuration file contains the settings for the Universal Proxy.
### It has four sections
### 	* Server settings
### 	* LastPass API settings
### 	* LDAP settings
### 	* RADIUS settings
### Fill Server settings and LastPass API settings first. Then fill LDAP settings if you plan to use
### Universal Proxy using LDAP or LDAPS or fill RADIUS settings if you are going to use RADIUS.
### If a value is not applicable for your case leave it as it is.
### For further information see the online documentation:
### 	https://support.lastpass.com/help/what-is-lastpass-universal-proxy
###
### Note, that it is also possible to configure Universal Proxy using the command line tool.
### Issue the following command in PowerShell to start the command line configuration tool:
### 	uproxy -configurationTool

## LDAP settings: set these values to configure Universal Proxy to be able to communicate with a LDAP server.
## Leave these values blank if you are not planning to use Universal Proxy for LDAP authentication.
## The ldap.admin.password field is applicable only if the server mode is LP.
## The ldap.address, ldap.port and ldap.tls fields can only be used if the server mode is either PLP or SFA.
## For an explanation about server modes see the documentation:
## 	https://support.lastpass.com/help/what-is-lastpass-universal-proxy#server_modes
## For the current server mode see the value of the server.mode variable in this file.
## Leave any value blank which is not applicable for your current setup.
##

# The address of the AD. Applies to server modes: [PLP | SFA]
ldap.address=172.19.0.5

# The port on which the AD expects authentication messages (default: LDAP: 389, LDAPS: 636). Applies to server modes: [PLP | SFA]
ldap.port=389

# The distinguished name of the LDAP admin user. Example: CN=admin,CN=Users,DC=domain,DC=com
ldap.admin=CN=testAdmin,CN=Users,DC=testproxy,DC=com

# The password of the LDAP admin user. Applies to server modes: [LP] only.
ldap.admin.password=your_password


# LDAP naming attribute: the name of the LDAP field in which the Windows user logon name is stored. Possible values: [cn | uid | userPrincipalName | sAMAccountName]
# ldap.attribute.login=sAMAccountName
ldap.attribute.login=sAMAccountName

Check the following:

• The ldap.admin field value must be the same as the Active Directory's distinguishedName field value.
• The maximum length of the sAMAccountName is 20 characters.
