Untouched server NW 6.5.7 DS 8.7.3.10 SMP which was used for LDAP
authentication for Apache suddenly started giving error:

Failed to authenticate full context on connection 0x9fc667e0, err = failed
authentication (-669)

I can connect to this LDAP server with no problems with LDAP browser 2.8.2

Anybody has any idea?

Thanks

Seb
