Methods

loginADUser(username: string, password: string, attributes?: Array): User|null

Attempts to authenticate a user with a given sAMAccountName and password. If unsuccessful, it returns null. If successful it returns a user object with:

• sAMAccountName
• givenName (firstname)
• sn (surname)
• telephoneNumber
• mail (email)
• l (location)
• ... any attributes included in the optional 3rd argument (an array of strings)

getADUserInfo(username: string, attributes?: Array): Promise<User|null> Authenticates with a default user whose sAMAccountName and password are defined in a .env file. If unsuccessful, it returns a Promise rejection with null. If successful it returns a Promise resolve with the user object:

• sAMAccountName
• givenName (firstname)
• sn (surname)
• telephoneNumber
• mail (email)
• l (location)
• ... any attributes included in the optional 3rd argument (an array of strings)

getADUserGroups(username: string, attributes?: Array): Promise<Array|null> Authenticates with a default user whose sAMAccountName and password are defined in a .env file. If unsuccessful, it returns a Promise rejection with null. If successful it returns a Promise resolve with the user's groups: [ Group { dn, cn, description, distinguishedName, objectCategory }, ... ]

getADUsersForGroup(groupname: string): Promise<Array|null> Authenticates with a default user whose sAMAccountName and password are defined in a .env file. If unsuccessful, it returns a Promise rejection with null. If successful, it returns a Promise resolve with a list of users belonging to the AD group: [ User { sAMAccountName, givenName, sn, mail, l, }, ... ]
