Hi, I’ve configured working LDAP server for authentication

When I’m logging with ldap user thi is log:  
awx.api.generics Login failed for user xxxxxxxx from 10.42.0.11

Why awx is not using ldap backend?  
Miscellaneous Authentication settings:

“awx.sso.backends.LDAPBackend”,  
“awx.sso.backends.TACACSPlusBackend”,  
“awx.main.backends.AWXModelBackend”

Hi Andrea

Can you please specify in detail what is the problem with the LDAP user login  
There is a known bug with awx Operator 0.13.0 or awx 19.3.0 where an LDAP user can login for the first time and then he struggles to login

Regards  
Abhinit
