Hi,

We are using Active Directory for user authentication, this being configured over ssl on port 636. This was working fine until this last weekend when we installed Defender on the Active Directory and some patching, On Monday AD users couldn’t login. In the logs I found

2023-03-13 19:57:05,849 WARNING [861e481d805442c8ae1b3d8e417129e8] django_auth_ldap Caught LDAPError while authenticating clubbing80: SERVER_DOWN({‘result’: -1, ‘desc’: “Can’t contact LDAP server”, ‘ctrls’: , ‘info’: ‘error:0A000086:SSL routines::certificate verify failed (EE certificate key too weak)’})

I have searched the history here and found AWX LDAPS authentication - disable REQUIRE CERT (google.com) .

in “/api/v2/settings/ldap/” I have tried to configure the following :

“AUTH_LDAP_CONNECTION_OPTIONS”: {
“OPT_REFERRALS”: 0,
“OPT_NETWORK_TIMEOUT”: 30,
“OPT_X_TLS_NEWCTX”: 0
},

but I still get the same error :

Please advise on next steps.

Hi!

If you are simply trying to disable cert requirement, your settings should look something like this

“AUTH_LDAP_CONNECTION_OPTIONS”: {
“OPT_X_TLS_REQUIRE_CERT”: 0,

“OPT_NETWORK_TIMEOUT”: 30,

“OPT_X_TLS_NEWCTX”: 0,
“OPT_REFERRALS”: 0}

Otherwise, seems like a LDAP server configuration issue
