Title: optional LDAP auth

Right now it just pops open the browser login dialog, we can add a nicer login page if we want.

example config:
```
ldap:
uri: ldaps://myldap.com:636
cachePolicy: maximumSize=10000, expireAfterWrite=10m
userFilter: ou=people,dc=yourcompany,dc=com
groupFilter: ou=groups,dc=yourcompany,dc=com
userNameAttribute: cn
groupNameAttribute: cn
groupMembershipAttribute: memberUid
restrictToGroups:
- user
- admin
- bots
connectTimeout: 500ms
readTimeout: 500ms
```
