LDAP authentication problem

[Domen Šetar <domen.setar@xxxxxxx>]

Hi Admins,

 

I have faced very strange problem in one of my postgresql servers. We use LDAP authentication.

 

Several colegues can't login with their AD accounts into the server. I found error messages in postgresql log:

 

2024-10-18 07:23:46 CEST [3203974]: [2-1] …  could not search LDAP for filter "(samaccountname=johndoe)" on server "adc1 adc2": Operations error

2024-10-18 07:23:46 CEST [3203974]: [3-1] … DETAIL:  LDAP diagnostics: 000004DC: LdapErr: DSID-0C090C78, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v4f7c

2024-10-18 07:23:46 CEST [3203974]: [4-1] … FATAL:  LDAP authentication failed for user "johndoe”

 

I can login with my AD account.

Ldapsearch works from the host.

My colegues can login with the same LDAP account to postgresql on antoher hosts.

 

I'm out of ideas what could be wrong.

 

Best regards!
