Gitlab Active Directory issues - gitlab-7.7.1_omnibus - active-directory

Question

I am having issues with Active Directory authentication via LDAP on Gitlab omnibus. I have tested the credentials and bind dn using ldapsearch and received a response with no issues, but for some reason I am not seeing any attempts at connecting when I login as an AD user on the gitlab frontend. I receive the error "Could not authorize you from Ldapmain because "Invalid credentials"." no matter if I'm using valid credentials or not.
I also receive the following from sudo gitlab-rake gitlab:check:
** Invoke gitlab:ldap:check (first_time)
** Invoke environment
** Execute gitlab:ldap:check
Checking LDAP ...
LDAP users with access to your GitLab server (only showing the first 100 results)
Server: ldapmain
Checking LDAP ... Finished
Please let me know if my explanation is not clear, or if you think that additional information would be helpful. I tried searching around and am not finding my exact issue.
My configuration is as follows:
gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = YAML.load <<-EOS # remember to close this block with 'EOS' below
main: # 'main' is the GitLab 'provider ID' of this LDAP server
## label
#
# A human-friendly name for your LDAP server. It is OK to change the label later,
# for instance if you find out it is too large to fit on the web page.
#
# Example: 'Paris' or 'Acme, Ltd.'
label: 'LDAP'
host: 'myadserver.my.domain.net'
port: 389
uid: 'sAMAccountName'
method: 'plain' # "tls" or "ssl" or "plain"
bind_dn: 'CN=Gitlab,OU=Service Accounts,OU=Washington\, D.C.,OU=United States,OU=NA,DC=my,DC=domain,DC=net'
password: 'mypasswrd'
# This setting specifies if LDAP server is Active Directory LDAP server.
# For non AD servers it skips the AD specific queries.
# If your LDAP server is not AD, set this to false.
active_directory: true
# If allow_username_or_email_login is enabled, GitLab will ignore everything
# after the first '#' in the LDAP username submitted by the user on login.
#
# Example:
# - the user enters 'jane.doe#example.com' and 'p#ssw0rd' as LDAP credentials;
# - GitLab queries the LDAP server with 'jane.doe' and 'p#ssw0rd'.
#
# If you are using "uid: 'userPrincipalName'" on ActiveDirectory you need to
# disable this setting, because the userPrincipalName contains an '#'.
allow_username_or_email_login: true
# Base where we can search for users
#
# Ex. ou=People,dc=gitlab,dc=example
#
base: 'OU=Washington\, D.C.,OU=United States,OU=NA,DC=my,DC=domain,DC=net'
# Filter LDAP users
#
# Format: RFC 4515 http://tools.ietf.org/search/rfc4515
# Ex. (employeeType=developer)
#
# Note: GitLab does not support omniauth-ldap's custom filter syntax.

This was, of course, a whitespace issue. See lines below:
gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = YAML.load <<-EOS # remember to close this block with 'EOS' below
main: # 'main' is the GitLab 'provider ID' of this LDAP server
## label
#
# A human-friendly name for your LDAP server. It is OK to change the label later,
# for instance if you find out it is too large to fit on the web page.
#
# Example: 'Paris' or 'Acme, Ltd.'
label: 'LDAP'
