Hi, I've been using IMAP with SASL for GSSAPI authentication and need to go back and compile some Kerberos IV support in so that our windoze clients (eudora and mulberry) can use the service. Kerberos (MIT v1.1.1) has been compiled with krb4 support. When I try to configure SASL I get the following error message: checking for krb.h... yes checking for krb_mk_priv in -lkrb... no checking for krb_mk_priv in -lkrb... (cached) no configure: warning: No Kerberos V4 found checking KERBEROS_V4... disabled Any ideas? Thanks, Alex.
