}


With first auth "mydomain" on location / all Ok.
But With second auth "mydomain2" on location /user  ask login and password
but not work

Log:
http_auth_ldap: Initial bind failed (49: Invalid credentials [80090308:
LdapErr: DSID-0C090400, comment: AcceptSecurityContext error, data 52e,
v1db1])

49: Invalid credentials talk about incorrect password. But i sure what
password is correct.

Has anyone had such problems?
