Hi! To get sasl 2.1.21 compiled on AIX 5.3, we had to do the following changes: aix> cd $SOURCE/cyrus-sasl-2.1.21 aix> cd config aix> vi ltconfig Change every "aix4*)" to "aix5*)" [in vi i.e. „:1,$s/aix4\*)/aix5\*)/g“ ] Did this changed in 2.1.22? If not, can you provide native AIX 5.3 support later? Hans
