Ok, Thanks a lot for that information. I appreciate it.

Now I have onother question about the kerberos Authenticaition.

I guided myself today using cgpguide pdf. I Have a windows server 2003 [SAVGATE.LOCAl] which is the Domain Controller (AD). (

I have the CGPro server in another domain [cgpro.linux.local], in a linux computer. (

I went and after installing the support tools in de Win. server (I needed ktpass), I created a user under Administrative Tools --> Active Directory Users and Computers in the user map. And then I made the keytab.

ktpass -princ imap/linux.local@SAVGATE.LOCAL -mapuser cgatepro -pass 1!2@3$ -out -crypto DES-CBC-MD5 -ptype KRB5_NT_SRV_HST

I imported this keytab to CGPRO webinterface under Users, Domains, CGPro.linux.local, Security, Kerberos.

Now I am trying to log in in webmail with this users and it does not work.

I may be so that I made a mistake somewhere or that I am not finished with the authentication.

Or did I misunderstood the whole point of kerberos authentication?
